evaluate 2x+3y if x=5 and y=2
To evaluate 2x + 3y when x = 5 and y = 2, we substitute these values into the expression:
2(5) + 3(2)
10 + 6
= 16
Therefore, if x = 5 and y = 2, 2x + 3y equals 16.
To evaluate 2x + 3y when x = 5 and y = 2, substitute the given values into the expression:
2x + 3y
= 2(5) + 3(2) [substituting x = 5 and y = 2]
= 10 + 6
= 16
Therefore, when x = 5 and y = 2, the value of 2x + 3y is 16.
To evaluate 2x + 3y when x = 5 and y = 2, you need to substitute these values into the expression and perform the necessary calculations.
Step 1: Replace x with its value of 5 and y with its value of 2 in the expression 2x + 3y.
2(5) + 3(2)
Step 2: Perform the multiplication operations first.
10 + 6
Step 3: Add the results of the multiplication operations.
16
Therefore, when x = 5 and y = 2, 2x + 3y evaluates to 16.
