What property was used in step 1 to arrive at step 2? Step 1: 5(x-7) = 55
Step 2: 5x-35 = 55
Step 3: 5x = 90
Step 4:
X = 18

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
