If x = 5, and y = 2, evaluate 5x - 2y.
Substitute x = 5 and y = 2 into the equation:
5x - 2y = 5(5) - 2(2)
= 25 - 4
= <<25-4=21>>21
Therefore, when x = 5 and y = 2, the value of 5x - 2y is 21.
To evaluate the expression 5x - 2y when x = 5 and y = 2, follow these steps:
Step 1: Substitute the values of x and y into the expression.
5(5) - 2(2)
Step 2: Simplify the expression inside the parentheses.
25 - 4
Step 3: Perform the subtraction.
25 - 4 = 21
Thus, when x = 5 and y = 2, 5x - 2y is equal to 21.
