2x+20=-6
Consider the first equation. Swap sides so that all variable terms are on the left hand side.
2x=-6-20
Subtract 20 from both sides.
2x=-26
Subtract 20 from -6 to get -26.
x=\frac{-26}{2}
Divide both sides by 2.
x=-13
Divide -26 by 2 to get -13.
x=-13 y=14 z=13 a=-9 b=14 c=13 d=-9
The system is now solved.
