Question

Solve the system of equations below by elimination. (Show your work) 4x+y=9 3x+2y=8

Answer 1

Answer:

(2,1)

Step-by-step explanation:

1 step:  -2(4x+y=9)

             3x+2y=8

2 step: -8x-2y=-18

             3x+2y=8

3 step: -5x=-10

divide by -5 both sides

x=2

Now we solve for y

choose an equation from above and subtitute the x for 2.

3(2)+2y=8

6+2y=8

subtract 6 from both sides

2y=2

Y=1
