Question

$$2m+3n-p+7m-2n,m=1,n=2,p=-1$$

Solve for m, n, p, o

$o=12$

Solution Steps

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

$$o=2\times 1+3\times 2-\left(-1\right)+7\times 1-2\times 2$$

Do the multiplications.

$$o=2+6+1+7-4$$

Add $2$ and $6$ to get $8$.

$$o=8+1+7-4$$

Add $8$ and $1$ to get $9$.

$$o=9+7-4$$

Add $9$ and $7$ to get $16$.

$$o=16-4$$

Subtract $4$ from $16$ to get $12$.

$$o=12$$

The system is now solved.

$$m=1$$ $$n=2$$ $$p=-1$$ $$o=12$$
