To determine

To calculate: The value of the expression 2x−y+2z .

Expert Solution & Answer
Check Mark

Answer to Problem 51S

The value of the expression 2x−y+2z is 9 .

Explanation of Solution

Given information:

The expression 2x−y+2z and value of x , y and z x=−1,y=3 and z=7 .

Formula used:

Order of operations is a method in which values of the variables are substituted in the expression to find its value and then mathematical operations are applied from left to right.

Calculation:

Consider the provided expression 2x−y+2z and the values of the variables as x=−1,y=3 and z=7 .

Recall that order of operations is a method in which values of the variables are substituted in the expression to find its value and then mathematical operations are applied from left to right.

Substitute x=−1,y=3 and z=7 in the expression 2x−y+2z and solve it further as,

  2x−y+2z=2(−1)−(3)+2(7)=−2−3+14=14−5=9

Thus, the value of the expression 2x−y+2z is 9.
