Front

The ordered pair that satisfies BOTH equations in the system is called the _____________________

Back

solution

Front

y=x+2

3y + x =14

What would you write for a substituted equation?

Back

3(x +2) +x = 14

Front

Substitute y = 4x into 5y - 2x = 18.

Back

5(4x) - 2x = 18

Front

Substitute y = 2x + 4 into 3x - y = 8

Back

3x - (2x +4) = 8
