Answer:

Explanation:

2x + -1y = -42

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'y' to each side of the equation.

2x + -1y + y = -42 + y

Combine like terms: -1y + y = 0

2x + 0 = -42 + y

2x = -42 + y

Divide each side by '2'.

x = -21 + 0.5y

Simplifying

x = -21 + 0.5y

hope helps you
