Unit 3 Day 2

Which equation would be used to solve for x?

• 2x - 30 = x - 12

• 2x - 30 + x - 12 = 90

• 2x - 30 + x - 12 = 100

• 2x - 30 + x - 12 = 180

Given m∠QST = 135°,

What equation would you use to find x?

• 3x + 1 + 2x - 6 = 135

• 3x + 1 = 2x - 6

• 3x + 1 + 135 = 2x - 6

• 2x - 6 = 135

Given m∠PRS = 98°,

What equation would you use to find x?

• 3x - 8 + 2x + 6 = 98

• 3x - 8 = 2x + 6

• 3x - 8 + 98 = 2x + 6

• 2x + 6 + 98 = 3x - 8
