3-50.

For the following equations, simplify and solve for the variable.  Record your work.

1. $2 x - 7 = - 2 x + 1$

Flip subtraction to addition.

Add $2x$ to both sides.

Add $7$ to both sides.

Divide by $4$ on both sides.

$2x+(−7)=−2x+1$

$4x+(−7)=1$

$4x=8$

$x=2$

1. $- 2 x - 5 = - 4 x + 2$

See the steps in part (a).
