Answer 2

Answer:

The value of the expression 2x - 2y will be 6.

Here, we are given the following linear equation: x - y = 3

now, in order to calculate the value of the expression 2x - 2y, we can simply multiply the given equation throughout by 2 as follows -

2(x - y) = 3 × 2

opening up the brackets and multiplying the terms on the right hand side of the equation, we get-

2x - 2y = 6

Thus, the value of the expression 2x - 2y comes out to be 6.
