Solving Two Variable Equations

Solve the equation: 2x + 3y = 8, given that x = 4.

• x = 4, y = 0

• x = 4, y = 2

• x = 4, y = 5

• x = 4, y = 3

Solve the equation: 5x - 2y = 7, given that y = 2.

Solve the equation: 3x - 2y = 5, given that y = -1.

Solve the equation: 4x - 3y = 9, given that y = 3.

• 9

• 6

• 4.5

• 3

Solve for y:
2x + 2y = 6

• y = - x + 3

• y = x + 3

• y = 2x +6

• y = - 2x + 6

-16x=2y-10

• 8x+y=5

• -16x-2y=10

• 16x+2y=-10

• 8x-y=-5

5x - y = 16

• -y = 5x + 16

• y = 5x + 16

• x = 5y - 16

• y = 5x - 16
