Solve: 7x = 3x + 24

• 10

• 4

• 6

• 14

Solve: 10x + 9 = 4x - 9

• 3

• 0

• -18

• -3

Solve the equation: 4x - 5x + 9 = 5x - 9

• x=3

• x=-3

• x=-9

• x=9

In order to solve an equation, we must get variables on one side of an equation, and constants on the opposite side.

• False

• True

x + 2y = 10

• y = -2x + 5

• y = -1/2x + 5

• y = -1/2x - 5

• 2y = -x + 10

Any point on the line x = y is of the form

• (k, -k)

• (0, k)

• (k, 0)

• (k, k)

Determine the values of x and y that satisfy the equations: 7x - 2y = 5 and 3x + 4y = 11

• x = 4, y = 3

• x = 2, y = 4

• x = 3, y = 2

• x = 5, y = 1

Find the solution to the system of equations: 4x - 3y = 5 and 2x + 7y = 1

• x = 2, y = -1

• x = -1, y = 2

• x = 5, y = 3

• x = 3, y = 4

If (2 ,0) is a solution of the linear equation 2x + 3y = k, then the value of k is_____

• 4

• 5

• 6

• 2
