In each case, you divide by the coefficient of x. Here, dividing by -1/7 is the same as multiplying by -7.

The first two answers are correctly chosen.

___

Then the ratio of the solutions is 63.7/1.3 = 49, easily calculated from the numbers given.

The second solution is 49 times the first.

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
