Question

Evaluate each expression if$x=-2,y=6,$and$z=5.$$-2x-3y+2z$

Short answer

The value of the expression$-2x-3y+2z$ is$-4.$

Step-by-step solution

Step-1 –Concept of evaluating the expression

The value of the variable in the expression can be calculated by putting the value of variable in the expression

Step-2 –Identifying the conditions

The given equation is$-2x-3y+2z$.and the values of the variables are,$x=-2,y=6,z=5.$

Step-3 –Simplify the expression

$\begin{array}{c}-2x-3y+2z=-2(-2)-3\left(6\right)+2\left(5\right)\\ =-4-18+10\\ =-14+10\\ =-4.\end{array}$
