Question

Solve the system of equations

Answer 1

x=3

y=1

Explanation:

9y= -9

Divide both sides by -9

y=1

2x + 4(1) = 10

2x = 6

x=3

(x,y)=(3,1)

Answer 2

x = 3

y = 1

Explanation:

(2x + 4y = 10) * 2 = (4x + 8y =20)

4x = 20 - 8y

Plug that into the other equation

(20 - 8y) - y = 11

-9y = -9

y = 1

Plug this value into one of the original equations

2x + 4(1) = 10

2x = 6

x = 3
