Question

Solve for x if:

y = 7
x = 5y + 2

Solve for y if:
k = 2
8k - 3y 10

Solve for y if:
m = 3
y = 5x - 15

Solve for x and y if:
y = -3x + 9
y = 8x - 2

Answer 1

Explanation:

Please the number given in place of its letter in your equation

x = 5y + 2 if y = 7

x = 5*7 + 2

x = 35 + 2

x = 37

Apply the same principle to the others
