Answer:
Solve for each for X.
Step-by-step explanation:
A. 7+2ax=13
1a. Subtract 7 from both sides, 2ax=6
2a. Divide both sides by 2, ax=3
3a. Divide both sides by a, x=3/a
B. -ax-20=-14
1b. flip the signs, ax+20=14
2b. subtract 20 on both sides, ax=-6
3b. divide both sides by a, x=-6/a
C. 4= (6/a)x+5
1c. Multiply both sides by a, 4a=6x+5a
2c. Subtract 5a from both sides, -a=6x
3c. Divide both sides by -1, a=-6x
