Question

Solve 2x - y = -6 if the domain is (-2,-1, 0, 1).

Answer 1

y = 2, y = 4, y = 6, y = 8

Explanation:

We are given an equation 2x - y = - 6.

We have to solve it.

The linear two-variable equation can be rearranged as y = 2x + 6 ........ (1)

Now, we need x values to get corresponding y values.{Since, there are two variables and only one equation}

It is given that the domain is (- 2, - 1, 0, 1).

Therefore, those are the x values for which we have to solve for y from equation (1).

For, x = - 2, y = 2( - 2 ) + 6 = 2 (Answer)

For, x = - 1, y = 2( - 1 ) + 6 = 4 (Answer)

For, x = 0, y = 2( 0 ) + 6 = 6 (Answer)

For, x = 1, y = 2( 1 ) + 6 = 8 (Answer)
