evaluate the expression 3x-2y for x=4 and y=5
To evaluate the expression 3x - 2y for x = 4 and y = 5, we substitute the given values into the expression.
Substituting x = 4 and y = 5, we get:
3(4) - 2(5)
= 12 - 10
= 2
Therefore, the value of the expression 3x - 2y for x = 4 and y = 5 is 2.
To evaluate the expression 3x - 2y for x = 4 and y = 5, substitute the given values into the equation:
3(4) - 2(5)
Simplifying the multiplication:
12 - 10
Finally, calculate the subtraction:
2
Therefore, when x = 4 and y = 5, the expression 3x - 2y equals 2.
To evaluate the expression 3x-2y for x=4 and y=5, you need to substitute the values of x and y into the expression and perform the necessary calculations.
Given:
x = 4
y = 5
Substituting these values into the expression 3x-2y, we get:
3(4) - 2(5)
Now let's simplify the expression:
3(4) = 12
2(5) = 10
Therefore:
12 - 10 = 2
So, when x=4 and y=5, the value of the expression 3x-2y is 2.
