Question

Substitution method to solve systems of equations. Enter as an ordered pair.

2x-y=10
3x-2y=8

Answer 1

(2x-y=10)x2
4x-2y=20
3x-2y=8

4x-3x=20-8
x=12

2(12)-y=10
y=14

(x,y)=(12,14)

Answer 2

The above stated is elimination method.

In substitution method,
You add y on both sides of the equation (1). You get an equation for 'y'.
Now, put this value of y in equation (2)
