X + 8 + 7x - 2 = 62
8x + 6 = 62
8x = 56
x = 56/8 = 7
so <STR = 7+8 = 15 and
< RTV = 7(7) - 2 = 47

Answer:
120 - (W*7)= A
Step-by-step explanation:
Let's say after 3 weeks. $120 is what he owes her in the beginning. He pays her $7/week.
After 3 weeks, he owes her 120 - (W*7)= A.
W=3, since we are 3 weeks along. So, after 3 weeks he still owes her
120 - (3*7)= A >>> 120 - 21= A >>> 99= A.
