Evaluate a linear expression for two variables

The video tutorial explains how to evaluate a mathematical expression by substituting given values for variables X and Y. The function involves multiplying X by 7 and subtracting Y. The instructor demonstrates the process by assigning X = 6 and Y = 5, performing the calculation, and arriving at the result of 37.

What are the given values for the variables X and Y in the problem?

• X = 5, Y = 6

• X = 7, Y = 5

• X = 6, Y = 5

• X = 5, Y = 7

What is the first step in evaluating the expression with the given values?

• Add X and Y

• Substitute the values of X and Y into the expression

• Multiply X and Y

• Subtract Y from X

What is the expression that needs to be evaluated?

• 7 * X + Y

• X + Y

• X - Y

• 7 * X - Y

What is the result of the expression after substituting X = 6 and Y = 5?

• 35

• 47

• 37

• 42

What is the final step in evaluating the expression?

• Add 5 to 42

• Multiply 7 by 5

• Subtract 5 from 42

• Divide 42 by 5
