I'm not sure what the question is but if your trying to find out how many t-shirts he bought it would be 7.
Here's why...
90$-34$= 56
56/8= 7
He could buy 7 shirts with the left over money he had.
Hope this answered your question. :)

Replace x with 1/2 then solve for y:
5(1/2) - 2y = 4
2 1/2 -2y = 4
Subtract 2 1/2 from each side:
-2y = 1 1/2
Divide both sides by -2:
y = 1 1/2 / -2
y = -3/4
