Answer:
8 (3x - 1) = 2 (9 – 7x)
24x - 8 = 18 - 14x
24x + 14x - 8 = 18 -14x + 14x
38x - 8 = 18
38x - 8 + 8 = 18 + 8
38x = 26
38x / 38 = 26 / 38
x = 13/19
Step-by-step explanation:
1. distribute both sides
2. add 14x to both sides
3. add 8 to both sides
4. divide both sides by 38 to get x
5 multiply by 8=40
40 divided by 20=2
