Answer explanation

Make sure you distribute the 3 first! Then combine your like terms.

Simplify the following expression:

-8 (5b + 2) -7 (b - 5)

• -33b + 19

• -47b² + 21

• 33b - 19

• -47b +19

Simplify the expression: 3x - 2y - 8 + 2 - 3x -3y

• 6x - 5y + 10

• -5y - 10

• 6x - y - 6

• -5y - 6

Simplify the following expression:
19 - ( 3 - 5b)

• 16 + 5b
• 21 + 5b
• 16 - 5b
• 21 - 5b

Simplify:

 $-7n-\left(-3-n\right)$
