Question

5x-3=4 (x+2)

Answer 1

5x-3=4x+8
5x-4x=8+3
x=11

Answer 2

yes the above is correct. So in these problems, you're working towards isolating the x. so distribute first..

4(x+2) and that gives you 4x+8

now put them equal..

5x-3=4x+8

from here, combine like terms. it's easier to work with positives, so subtract 4x from both sides.

x-3=8

now, isolate the x
to do so, add 3 to each side

-3+3=0 and 8+3=11

voila! x=11 :)
