Question

$$3p+n-m+2n,m=1,n=2,p=-1$$

Solve for m, n, p, o

$o=2$

Solution Steps

Consider the fourth equation. Insert the known values of variables into the equation.

$$o=3\left(-1\right)+2-1+2\times 2$$

Do the multiplications.

$$o=-3+2-1+4$$

Add $-3$ and $2$ to get $-1$.

$$o=-1-1+4$$

Subtract $1$ from $-1$ to get $-2$.

$$o=-2+4$$

Add $-2$ and $4$ to get $2$.

$$o=2$$

The system is now solved.

$$m=1$$ $$n=2$$ $$p=-1$$ $$o=2$$
