• x = 2

• x = 3

• x = 4

• x = 5

Select all the equations that have no solution.

• -2(x - 3) = -2x + 6

• x + 6 = 5 + x

• 4(x + 1) = 3(x + 2)

• 5 - 3x = -3x + 4

• 4 - 4x = 3x + 2

Miya solved the equation incorrectly. Identify Miya’s error and solve the equation

• Miya should have multiplied both sides by 6.

• Miya should have added 3 to both sides.

• Miya should have subtracted 9 from both sides.

• Miya should have divided by 2 instead of 3.

The formula to calculate the perimeter of a rectangle is p = 2l + 2w . Which equation is correct when solving for w?

• w = 2p + 2l

• w = 2p - 2l
