7-66.

1. $2(3x−4)=22$

Distribute, then simplify.
$6x−8=22$
$6x=30$

$x=5$

1. $6(2x−5)=−(x+4)$

Begin this problem by distributing the $6$ and the negative that are outside of the parentheses, then simplify by isolating the variable onto one side of the equation.

$x=2$

1. $2−(y+2)=3y$

Use the same methods outlined in parts (a) and (b).

1. $3+4(x+1)=159$
