1.5x%2B7y=76
2.6x-8y=91
From eq. 1,
5x%2B7y=76
5x=-7y%2B76
x=%28-7y%2B76%29%2F5
Substitute into eq. 2,
2.6x-8y=91
6%28-7y%2B76%29%2F5-8y=91
6%28-7y%2B76%29-40y=455
-42y%2B456-40y=455
-82y=-1
highlight%28+y=1%2F82%29
Then use eq. 1,
5x=-7y%2B76
5x=-7%2F82%2B76
5x=-7%2F82%2B6232%2F82
5x=6225%2F82
highlight%28+x=1245%2F82%29
