X-y=3 work out the value of 5(x-y)

work out the value of 2x-2y
k
work out the value of y-x

If x - y = 3

Work out the value of 5(x - y)

x - y = 3 ( Given )

5(x - y) = 5 × 3 = 15 [ as x - y = 3 ]

_____________________________________

If x - y = 3

Work out the value of 2x - 2y

x - y = 3 ( Given )

2x - 2y = 2(x - y) = 2 × 3 = 6 [ as x - y = 3 ]

If x - y = 3

Work out the value of y - x

x - y = 3 ( Given )

y - x = -3 [ as x - y = 3 ]
