Answer:

x = 4

Step-by-step 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

       [tex]\frac{12x}{12} = \frac{48}{12}[/tex]

x = 4

Answer:

x = 4

Step-by-step 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
