How do I solve 3 (x + 20) + (x + 20) + x = 180?

3x + 60 + x + 20 + x = 180

5x + 80 = 180

5x = 100

x = 20

3 (x + 20) = 3x + 60

equation is 3x + 60 + x + 20 + x = 180

collect terms: 5x + 80 = 180

5x - 80 = 180 - 80

5x = 100

x = 100 / 5

x = 20

Substituting into equation answer 20 we get;

3 ( 20 + 20 ) + ( 20 + 20 ) + 20 = 180

3 x 40 + 40 + 20 = 180

120 + 40 + 20 = 180

180 = 180

To solve 3(x+20)+(x+20)+x=180

solution:

firstly open the brackets

3x + 60 + x + 20 + x = 180

collect like terms

3x + x + x = 180 - 60 - 20

5x = 100

x = 100/5

x = 20

firstly u need to distribute 3(x + 20) and get 3X + 60 and + with x + 20 + x....u need to separate between the x and the number..so it'll be like this

3x + 60 + x + 20 + x =180

combine the x's, 3x + x + x =5x

then combine the number,60 + 20=80

now u get 5x + 80 = 180

then u bring the 80 to the right,the '+' will change into '-' so ull get.....5x=180 - 80

solve the minus operation..5x =100

now u need to get x,it has to be alone that means

x =100/5...

so x is 20....

p/s: u have to do it carefully and always think,its just a simple question.....gud luck

There are algebraic rules of sequence (the order in which you perform the indicated calculations) - for instance, if there are no parentheses present, one would do multiplication and division first and then do addition and subtraction. (E-mail me if you want a better example of this.)

In your example, the presence of parentheses doesn't make any real difference, but you should keep the concept in mind. But here is what your formula really means:

3 (x + 20) = 3*x + 3*20 = 3x + 60

So the full expression is:

3x + 60 + x + 20 + x = (3x + x +x) + (60 +20) = 5x + 80

Setting that expression back into the equality:

5x + 80 = 180

Subtracting 80 from both sides:

5x = 100

Divide both sides by 5:

x = 20

First, distribute the 3 into the (x+20) and get:

3x + 60 + x + 20 + x = 180

On the left side, 60+20 = 80, and on the right side, you have 180. So subtract 80 from both sides:

3x + x + x = 100

Now combine ''like terms'' , like the x's on the left:

5x = 100

Now divide both sides by 5, because you need x by itself:

x = 20

Good luck!

3 (x + 20) + (x + 20) + x = 180

3x + 60 + x + 20 + x = 180 -expanding

= 3x + x + x + 60 + 20 =180 -Grouping like terms

5x + 80 = 180

5x = 180 - 80

5x = 100

x = 100/5 =20

3 (x + 20) + (x + 20) + x = 180

3x + 60 + x + 20 + x = 180

3x + x + x = 180- 60 -20

5x = 100

x = 100/5

x = 20

3x + 60 + x+ 20+ x =180

5x + 80 =180

5x = 180 - 80

5x = 100

x = 20

p/s:do you know that the number inside of the brackets hav to be times with the number outside of the bracket

*2(y + 9)..means...2 x y.=2y.and 2 x 9.=18..so the overall answer for this example is ..= 2y + 18

3 * (x+20) is:

3*x=3x

3*20=60

(x+20)=x+20

3x + 60 + x + 20 +x =180

Add all the like terms.

5x+80=180

Subtract 80 from both sides.

5x=100

Divide by 5.

x=20
