Question

Complete the solution of the equation. Find the value of y when x equals -14. -6x + 6y = 42

Answer 1

Just plug in the x value where the x is in the equation.

-6(-14) + 6y = 42

84 + 6y = 42

84 - 84 + 6y = 42 - 84

6y = -42

6y / 6 = -42 / 6

y = -7

Answer 2

x = -14

-6(-14) + 6y = 42

84 + 6y = 42

subtract 84 from both sides: 6y = -42

divide by 6: y = -7

when x = -14, y = -7
