Step-by-step explanation:

1. 3a+10b+4a-4b

=3a+4a+10b-4b

=7a+10b-4b

=7a+6b

2. part a: x+(-3)=7

x-3=7

x-3+3=7+3

x=10

2. part b: 2x-2=-12

2x-2+2=-12+2

2x=-10

-10 ÷ 2

x=-5

3. 2(m + 6) = 24

2(m + 6) = 24

÷2             ÷2

m+6=12

m+6-6=12-6

m=6

4. -4x+8<32

-4x+8-8<32-8

(-4x)(-1)<(24)(-1)

4x>-24

÷4    ÷4

x>-6

step-by-step explanation:

y/x of point b= y/x of point a
