x-2x=-3
Consider the first equation. Subtract 2x from both sides.
-x=-3
Combine x and -2x to get -x.
x=\frac{-3}{-1}
Divide both sides by -1.
x=3
Fraction \frac{-3}{-1} can be simplified to 3 by removing the negative sign from both the numerator and the denominator.
y=4\times 3
Consider the second equation. Insert the known values of variables into the equation.
y=12
Multiply 4 and 3 to get 12.
z=12
Consider the third equation. Insert the known values of variables into the equation.
x=3 y=12 z=12
The system is now solved.
