6) 8=4(x−2)+4

8=(4)(x)+(4)(−2)+4

8=4x+−8+4

8=(4x)+(−8+4)

8=4x+−4

8=4x−4

Flip the Equation

4x−4=8 =

4x−4+4=8+4

4x=12=

4x/4 =12/4 = 3

x = 3

---------------------------------------------------------

7) x−4+2x=14

x−4+2x=14

x+−4+2x=14

(x+2x)+(−4)=14

3x+−4=14

3x−4=14

=

3x−4+4=14+4

3x=18

3x/3 = 18/3 = 6

x = 6

---------------------------------------------------------

8) 4(y+1)=−8

=

4(y+1)=−8

(4)(y)+(4)(1)=−8

4y+4=−8

=

4y+4−4=−8−4

4y=−12

4y/4 = −12/4 = -3

y= −3

---------------------------------------------------------

9) -2(d+6)/-2 = -10/-2

d+6 = 5

d+6-6=5-6

Simplify: d = -1
