How do you solve 23[72(4x)]=2x1?

1 Answer

x=34

Explanation:

this is a multi-step equation.

the first step is to simplify the contents of the 'square bracket'

23(78+2x)=2x1

now simplify contents of 'new bracket'

23(1+2x)=2x1

now multiply the bracket by - 3

2+36x=2x1

now collect like terms to separate sides of the = sign

2+3+1=2x+6x

6=8x ( divide both sides by 8 to obtain x )

68=8x8x=34
