15x-49+2x=36
Consider the first equation. Add 2x to both sides.
17x-49=36
Combine 15x and 2x to get 17x.
17x=36+49
Add 49 to both sides.
17x=85
Add 36 and 49 to get 85.
x=\frac{85}{17}
Divide both sides by 17.
x=5
Divide 85 by 17 to get 5.
x=5 y=22 z=22 a=22 b=22 c=22 d=22
The system is now solved.
