→ 8x - 4

B) 3(x + 7) + 2(-x + 4) + 5x

→ 3x + 21 - 2x + 8 + 5x

→ 6x + 29

Answer 2

Answer:

A) 8x - 4

B) 6x + 29

Step-by-step explanation:

A) -2x + 5 + 10x - 9 : given

= (10x - 2x) + (5 - 9) : put like terms together

= 8x - 4 : group

B) 3(x + 7) + 2(-x + 4) + 5x : given

= 3x + 21 - 2x + 8 + 5x : expand

= (3x - 2x + 5x) + (21 + 8) : put like terms together

= 6x + 29 : group
