Answer:

x=5, y=2

Step-by-step explanation:

1) Subtract 2y from both sides of x+2y to get x=9-2y

2) Substitute x into the first equation to get 3(9-2y)-2y=11

3) Solve for y (y=2)

4) Plug y into either equation: x+2(2)=9 x=5

5) The answer is (5, 2)

3 = -2x + 1 what is the value of x

DerKrebs [107]

Subtract 1 from both sides

3 - 1 = -2x

Simplify 3 -1 to 2

2 = -2x

Divide both sides by -2

-1 = x

Switch sides

x = -1
