Solve the equation: 3 (-x+4) = 20x-7

1 Regroup terms

3 (4-x) = 20x-7

2 Expand

12-3x=20x-7

3 Add 3x to both sides

12=20x-7+3x

4 Simplify

20x-7+3x to 23x-7

12=23x-7

5 Add 7 to both sides

12+7=23x

6 Simplify 12+7 to 19

19=23x

7 Divide both sides by 23

19/23 = x

8 Switch sides

x = 19/23
