X equals 1 and 2. When you put 1 into f(x) you get 2 and when you put 1 into g(x) you get 1 as well. The same for 2...but not the same for 3.
The error is in the second step they subtracted 3 from both sides but it was a 3x, which you can not do.
Correction.
9x+18+3x=1
12x+18=1
12x=-17
x=-17/12

50k is the same as 50,000
73% = 73/100 = 0.73
Multiply 50,000 with 0.73
50,000 x 0.73 = 36500
You spend $36500.
Subtract 36500 from the total
50,000 - 36,500 = $13,500
$13,500 is the amount of money you have left.
hope this helps
