Question

Solve for x: 4(3x−7) = 20. Question 3 options: 2/3 16 5 4

Answer 1

x = 4

Explanation:

Given

4(3x - 7) = 20 ( divide both sides by the multiplier 4 )

3x - 7 = 5 ( add 7 to both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Answer 2

x = 4

Explanation:

Work the problem out

4(3x - 7) = 20

Get x to be alone on one side

12x - 28 = 20

+ 28 + 28

Then divide 12x by 12 to get x alone (divide both side by 12)

12x = 48

`(12x)/(12) = (48)/(12)`

x = 4
