Ihave been ask for this questions too many times would some one me, i would be for you forever. you very much.

b. The solutions are the same. It means that the equations have identical solutions.

c. 4x+ 6= 28 ( I have subtracted 4 from each side)

8x+ 20= 64 ( In this case, multiplied by 2 on both sides)

2x+ 5= 16 ( divided by 2 on both sides)

d. 4x+10= 32

4x+ 10- 10= 32- 10 (subtracted 10 on both sides)

4x= 22

x= 22÷4 ( divided by 4 on each side)

x= 5.5

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

there is no grid
