Evaluate 8x -4 y when x=2 and y=3
To evaluate 8x - 4y when x = 2 and y = 3, substitute these values into the equation:
8(2) - 4(3) = 16 - 12 = 4.
Therefore, when x = 2 and y = 3, 8x - 4y equals 4.
To evaluate 8x - 4y when x = 2 and y = 3, substitute the values of x and y into the expression:
8(2) - 4(3)
Now, simplify the expression:
16 - 12
Finally, calculate:
16 - 12 = 4
Therefore, when x = 2 and y = 3, 8x - 4y equals 4.
To evaluate the expression 8x - 4y when x = 2 and y = 3, substitute the given values into the expression:
8(2) - 4(3)
Now, perform the multiplication first:
16 - 12
Finally, subtract:
4
Therefore, when x = 2 and y = 3, the expression 8x - 4y evaluates to 4.
