Question

Solve the equation for x: 3x + 6y = 15.
Answer

x = 15 – 6y

x = 5 – 2y

x = 12 – 6y

x = 5 – 6y

Answer 1

: 3x + 6y = 15.
subtract 6y
3x=15-6y
divide by 3
x=5-2y

Answer 2

3x + 6y = 15
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
3x + 6y + -6y = 15 + -6y
Combine like terms: 6y + -6y = 0
3x + 0 = 15 + -6y
3x = 15 + -6y
Divide each side by '3'.
x = 5 + -2y
x = 5 + -2y

Answer 3

x = 5 -2y
