Question

Find the solution of the system of equations.

-10x-y=27
-4x-y=9

Answer 1

x=−1/10 y+ −27/10

x=−1/4 y+ −9/4

Explanation:

−10x−y=27

Step 1: Add y to both sides.

−10x−y+y=27+y

−10x=y+27

Step 2: Divide both sides by -10.

−10x /−10= y+27 /−10

x=−1/10 y+ −27 /10

−4x−y=9

Step 1: Add y to both sides.

−4x−y+y=9+y

−4x=y+9

Step 2: Divide both sides by -4.

−4x /−4= y + 9/−4

x= −1/4 y + -9/4

Answer 2

(-3,3)

Explanation:

y=3

x=−3
