6-143.

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

1. Solve for $x$: $2x + 22 = 12$

$x = −5$

1. Solve for $y$: $2x-y=3$

Add $y$ to both sides of the equation.

How can you move $3$ to isolate $y$ on the right side of the equation?

1. Solve for $x$: $2x+15=2x-15$

If you subtract $2x$ from both sides of the equation, what kind of statement is left? Is there any value of $x$ that will make this equation true?

1. Solve for $y$: $6x + 2y = 10$

$y=5-3x$
