4-114.

Solve each equation below for the indicated variable, if possible. Show all steps.

Solve for $x$ : $2x+22=12$
Hint (a):
Solve by isolating the variable on one side of the equation by subtracting $22$ from both sides.
$2x=12−22$
$2x=−10$
Answer (a):
$x=−5$

Solve for $y$ : $2x-y=3$
Hint (b):
Solve by isolating $y$ on one side of the equation, and then simplify as much as possible.
$2x=y+3$
Subtract $3$ from both sides.
Answer (b):
$2x−3=y$

Solve for $x$ : $2x+15=2x-15$
Hint (c & d):
Use the same strategy shown in parts (a) and (b) to solve parts (c) and (d).

Solve for $y$ : $6x+2y=10$
Answer (d):
$y=5−3x$
