y=17/7
x=123/7
Explanation:
2x=74-8y
x = (74-8y) / 2
x=2 (37-8y) / 2
x=37-8y
3 (37-8y) - 4y=43
111-24y-4y=43
111-43=24y+4y
68=28y
y=68/28
y=17/7
x=37-8 (17/7)
x=37-136/7 = (37*7-136) / 7 = (259-136) / 7
x=123/7

(2x+8y) / 2=74/2
x+4y=37
x=37-4y
3 (37-4y) - 4y=43
117 - 12y - 4y = 43
-16y = 74
y=4.625
x=37 - 4 (4.625)
x = 37 - 18.5
x = 55.5
so y=4.625,x=55.5
