Evaluate 5x-\dfrac xy5x−

y

x

​

5, x, minus, start fraction, x, divided by, y, end fraction when x=4x=4x, equals, 4 and y=2y=2y, equals, 2.

Answer 1

5x - (x/y) = 18 when x=4 and y=2

Explanation:

5x - (x/y)

When x=4 and y=2

Substitute the value of x=4 and y=2 into the expression

5x - (x/y)

5(4) - (4/2)

Multiply 5 by 4 and divide 4 by 2

=20 - 2

Subtract 2 from 20

=18

5x - (x/y) = 18 when x=4 and y=2
