7x+5-3x=-11
Consider the first equation. Subtract 3x from both sides.
4x+5=-11
Combine 7x and -3x to get 4x.
4x=-11-5
Subtract 5 from both sides.
4x=-16
Subtract 5 from -11 to get -16.
x=\frac{-16}{4}
Divide both sides by 4.
x=-4
Divide -16 by 4 to get -4.
y=-4
Consider the second equation. Insert the known values of variables into the equation.
z=-4
Consider the third equation. Insert the known values of variables into the equation.
x=-4 y=-4 z=-4
The system is now solved.
