Math Help. Just one Question?

Distribute the 3 through the parenthesis. (multiply the numbers inside of the parenthesis by the 3)

So it looks like:

3x+15=30

Then Subtract 15 from both sides.

So it looks like:

3x=15

Then Divide both sides by 3 to get the variable by itself.

So it looks like this:

x=5

this is a distributive property question. So you multiply 3 with each of the values in the parenthesis.

3(x+5)=30

3*x + 3*5=30

3x + 15= 30

- 15 -15 <--- inverse property, subtract 15 from each side

3x + 0 = 15

3x/3 = 15/3 <---- to isolate the x on the left side

x = 5

3 (x + 5) = 30 * write original equation.

3x + 15 = 30 * distribute the 3 to the number in the parenthesis.

3x = 15 * subtract 15 from 30 to get 15.

x = 5 * divide 15 by 3.

i hope this helped........

foil the 3 in:

3x+15=30 (subtract 15 from 30)

3x=15 (divide by 3)

x=5

3(x+5)=30

3*x=3x

3*5=15

3x+15=30

-15 -15

3x= 15

x= 5

x+5=10

x=5

3x + 15 = 30

then

3x = 15

x = 5

How to work the problem:

Divide 3 from both sides so....

x + 5 = 10

Subtract 5, therefore:

x = 5

3x + 15 = 30

then

3x = 15

x = 5

3x+15=30

3x=30-15

3x=15

x=5
