============
2x-3y=-11
3x+27y=29
============

system%289%2A2x-9%2A3y=9%28-11%29%2C3x%2B27y=29%29

system%2818x-27y=-99%2C3x%2B27y=29%29

Add the two equations' corresponding members.
21x%2B0=-70
x=-70%2F21
x=-7%2A10%2F%287%2A3%29
highlight%28x=-10%2F3%29

system%283%2A2x-3%2A3y=-33%2C2%2A3x%2B2%2A27y=2%2A29%29

6x-9y=-33%2C6x%2B54y=58

Subtract corresponding members.
0%2B63y=91
