Evaluate the expression for the given values of the variables.

evaluate 9p − 8q for p = 4 and q = −8.

the expression is equal to .

The expression 9p − 8q for p = 4 and q = −8 is equal to 100

Given that we have to evaluate expression for the given values of the variables

Expression is:

⇒ 9p − 8q

Given that p = 4 and q = -8

Let us substitute the given values of p = 4 and q = -8 in given expression and evaluate it

⇒ 9p − 8q = 9(4) - 8(-8)

⇒ 9p - 8q = 9(4) + 8(8)

Upon multiplying the terms we get,

⇒ 9p - 8q = 36 + 64 = 100

Thus the expression is equal to 100
