Evaluate the expression
(x−1) (y+1) when x=3 and y=2
.
Plug in the values of x and y into the expression:
(3-1)(2+1) = 2(3) = 6
To evaluate the expression (x−1) (y+1) when x=3 and y=2, substitute the given values for x and y into the expression and perform the arithmetic:
(3−1) (2+1) = (2)(3) = 6
To evaluate the expression (x−1) (y+1) when x = 3 and y = 2, you need to substitute the values of x and y into the expression and perform the operation.
Here are the steps to evaluate the expression:
1. Replace x with 3 and y with 2 in the expression:
(3−1) (2+1)
2. Simplify the parentheses:
(2) (3)
3. Multiply the numbers inside the parentheses:
2 * 3 = 6
Therefore, the value of the expression (x−1) (y+1) when x = 3 and y = 2 is 6.
