Question

Which ordered pair is a solution of the system of equations? y= 3x-1 and y= 5x + 1

Answer 1

x = -1

Explanation:

y = 3x - 1

y = 5x + 1

We can set these equations equal to each other, since they are both y.

3x - 1 = 5x + 1

-3x -3x

-1 = 2x + 1

-1 - 1

-2 = 2x

Divide by 2 on both sides.

x = -1
