What is the value of x in the solution to this system of equations?

5x = 2y + 8

y = -3x + 7

• 2

• -2

• 1

• -1

Which inequality describes all the solutions to 4 (2 - x) > -6x + 12 ?

• x > 2

• x > -2

• x > 10

• x > -10

Solve the equation:

5x - (5 - 2x) + 10 = 2x + 3(2x - 2)

• x = 11

• x = 1

• x = -11

• x = -1

• {(1, 2), (2, 3), (3, 4), (4, 5)}

• {(2, 5), (3, 5), (4, 5), (6, 5)}

• {(5, 4), (4, 3), (3, 2), (2, 1)}
