Question

Which ordered pair is a solution to the equation?

Answer 1

(1,2)

Explanation:

Solving the equation:

3x + 3y = -x + 5y

Subtract 3y to both sides,

3x = -x + 5y - 2y

Combine like terms,

3x = -x + 2y

Add x to both sides,

3x + x = 2y

Combine like terms,

4x = 2y

2y = 4x

y = 4x/2

y = 2x

When x = 1 , y = 2*1 = 2
