I need some help with algebra. I have to find out what the letter is.?

1. Combine the numbers with variables. Which is 2x. Subtract 2 from both sides. then divide by 2 on both sides.

If two numbers have variables that are the same, they can be combined. Such as 3x-5x. that would be -2x. then you have to get the variable on one side of the equation. If you subtract or divide from one side, (to do the opposite, like 2x/2 to get x by itself) you have to do it to the other side as well. Hope that helped.

1) 6x - 4x + 2 = 10

Bring all like terms to the same side of the equals sign:

6x - 4x = 10 - 2

Remember that numbers change from + to -, or from - to + when they move across the equals sign.

2x = 8

x = 4

2) 4 + 10x = 18 + 17x

4 - 18 = 17x - 10x

-14 = 7x (Divide both sides by 7 to find 1x)

-2 = x

I'll just give you the answers now.

3) 2

4) 20

5) 3

6) 5

7) 7

8) 3

9) 3

10) -2

11) 7

12) -3

13) -3

14) 3

15) 2

16) 5

17) 4

18) 5

19) 9

20) 7

You should be able to work these out by yourself now. You just need to move all like terms on to the same side being careful of whether they become minus or positive. Then divide it until you have x = ......

A tip: move the terms so that the unknown quantities are positive in the end.

i wont tell you the answer, but ill tell you how to solve!

1: 6x - 4x + 2 = 10

first, simplify. 6x-4x=2x.

2x + 2 = 10.

then, subtract the 2 from both sides.

2x = 8

divide both sides by 2

x=4

another one:

5: 6x - 2 = x + 13

when you have x on both sides, you have to subtract/add it from one side. in the case, subtract the x on the right side from both sides.

5x - 2 = 13

then, add 2 to both sides

5x = 15

divide both sides by 5

x = 3

one last one:

18: 4p - 10 = p + 3p - 2p

simplify the right side. p + 3p = 4p. 4p- 2p = 2p.

so now you have: 4p - 10= 4p.

take a look at this equation. how can 4p - 10 = 4p?? it doesnt make sense!! so this equation is 'no solution'.

i hope i helped; i know its confusing when someone tries to explain things over the computer.

between Albert and Leo you have all the solutions. rationalization 7. Black is 7, purple is 6, blue is 5......... brown is 4, green is 3, yellow is two, purple is a million. (they are the values in factors for potting the various colorations in a activity of snooker) As questions 7 and 10 (snooker and cricket) are extra British than American., i think that 9 is 4 communities get to the Semi Finals of the F.A. Cup. The F.A. Cup (to grant that's appropriate call The soccer association project Cup) is the main in call for soccer (soccer) opposition interior the worldwide, in all hazard much extra in call for than the worldwide Cup!).

1. 4

5. 5

No one can answer all these questions for u. You need to ask ur teacher or take some extra classes.

Hope u get the answers by yourself.

you need to learn this. Sorry, but this math is necessary.
