Question

What is the value of x in the equation 2x + 3y = 36, when y = 6?
8
9
27
36

Answer 1

9

Explanation:

Answer 2

x = 9

Explanation:

2x + 3y = 36 (subtract 3y from each side)

2x = 36 - 3y (divide both sides by 2)

x = (36/2) - (3/2)y

x = 18 - (3/2)y

when y = 6

x = 18 - (3/2)y

x = 18 - (3/2)(6)

x = 18 - (3)(3)

x = 18 - 9

x = 9
