It is 29 I might be wrong though
The answer is 17/18.
You need to make the denominator the same on all the fractions.
Hope this helps.
The answer to your question is x=-2y+4
You end with 210.85. add 75.50 and 55.25 together you get 130.75. 130.75-25.15-18.65 = 86.95. 210.85-86.95= 123.90 work backwards.
