Question

The steps below show the incomplete solution to find the value of x for the equation 7x 8 − 3x = −6 10: Step 1: 7x 8 − 3x = −6 10 Step 2: 7x 8 − 3x = 4 Step 3: 4x 8 = 4 Which of these is most likely the next step? 4x = 12 4x = 4 4x = −4 4x = −12.

Answer 1

4x = −4

Explanation:

Question 2

2(2x − 5 − 4) = 160 − 17

4x-10-8 = 160-17

4x-18=143

4x = 161

x=40.25

Question 3

4(2z + 3) = 12

8z +12 = 12

8z = 0

z = 0

Question 4

5(2x − 6) + 20 = 10

10x-30+20=10

10x-10=10

10x =20

x=2

Question 5

5x + 10 = 5x − 8

5x+18=5x

18=0

Zero solutions
