Answer:
MARK ME AS BRAINLIST
Step-by-step explanation:
Simplifying
5x + -7y = -52
Solving
5x + -7y = -52
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
5x + -7y + 7y = -52 + 7y
Combine like terms: -7y + 7y = 0
5x + 0 = -52 + 7y
5x = -52 + 7y
Divide each side by '5'.
x = -10.4 + 1.4y
Simplifying
x = -10.4 + 1.4y
