Question

What is the first step in solving 4(x + 2) = 10 + x?

Answer 1

Expand the left hand side.

Answer 2

Distribute by multiplying 4 by the terms in the parenthesis.

Multiply by 4 on both sides.

Subtract 2 on both sides.

Subtract x on both sides.


sorry forgot this part

Answer 3

Well that pretty much explains it all =)

Answer 4

Yes it does!

Answer 5

i came up with x=2

Answer 6

That can't be right! If we expand the brackets we get 4x+8 = 10 + x.

This can be rearranged to 3x = 2 and x = 2/3, which is right.

Answer 7

The previous explanation from @halo1996 explained the wrong method!

Answer 8

Oh I see, I didn't read it properly - I took it to be a step-by-step, but it was asking which the first step would be. Which is distributing the 4:

4(x + 2) = 10 + x
4x + 8 = 10 + x
3x = 2
x = 2/3
