Question 1025732
Hi there,
2x+4y=76
y=3/4x+4 
Sort 
2x + 4y = 76.......(1)
-3/4x + y = 4......(2)
Multiply Eq(2) by 4
2x + 4y = 76.......(1)
-3x + 4y = 16......(2)
Subtract Eq(2) from Eq(1)
5x = 60
x = 12
Substitute x = 12 into Eq(1)
2x + 4y = 76
2(12) + 4y = 76
24 + 4y = 76
4y = 76 - 24
4y = 52
y = 13
{12,13}
Hope this helps :-)
