Answer 2

Step-by-step explanation:

a. -3x from x

• x-(-3x)
• x+3x
• 4x

b. (2x-y) from (4x+3y)

• (4x+3y)-(2x-y)
• 4x+3y-2x+y
• 4x-2x+3y+y
• 2x+4y

c. 3(b-5) from 7(a+5)

• (3b-15) from (7a+35)
• (7a+35)-(3a-15)
• 7a+35-3a+15
• 7a-3a+35+15
• 4a+50

d. 2a²+3b²+2a from 5a+b

• (5a+b)-(2a²+3b²+2a)
• 5a+b-2a²-3b²-2a
• 3a-2a²-3b²+b

e. 2uv-3v²-5u² from 4u²-2v²-3vu

• (4u²-2v²-3vu)-(2uv-3v²-5u²)
• 4u²-2v²-3vu-2uv+3v²+5u²
• u²+v²-5uv
