4x- (3x+2)= 7x-2
What’s the answer?

first remove the parrenteses

so from this 4x- (3x+2)= 7x-2

to this 4x- 3x+2= 7x-2

then change the + to a -

so 4x- 3x- 2= 7x-2

then cancel equal terms on both sides of the equation so

4x- 3x= 7x

then collect like terms x =7x

then move the variable to the left hand side and change the sign

x- 7x = 0

next collect like terms

-6x =0

then divide both sides of the eqution by -6

so the awnse is x=0
