Unit 1 Review: combining like terms and solving

Use the distributive property to write an equivalent expression.
-8(z - 5)

• -8z - 40
• -8z + 40
• -8z - 13
• -8z - 13

Expand using the distributive property

-2(3x + 4y + 1)

• -6x + 8y + 2

• -6x - 8y + 2

• -6x - 8y - 1

• -6x - 8y - 2

Simplify the following expression by combining like terms:
3(2x - 4) + 6x - 1

• 12x - 13
• 12x - 5
• 11x - 2
• -x

Simplify:
4(8x + 1) - 6(1 - 8x)

• -80x - 2
• 80x + 2
• -80x + 2
• 80x - 2
