Question

Find a solution to the linear equation - 2x – 2y = 8 by filling in the boxes with a valid value of x and y.

Answer 1

The first box is -4 and the next box is 0

Answer 2

`-2(-4)-2(0)=8`

Explanation:

Given

`2x - 2y = 8`

Required

Gaps: -2( )-2( )=8

Fill in in the gaps

The are numerous solutions to this.

One of them is:

Assume y = 0.

So, we have:

`-2x - 2*0 = 8`

`-2x - 0 = 8`

`-2x = 8`

Divide through by -2

`(-2x)/(-2)= (8)/(-2)`

`x= -4`

Fill in the gaps with these values of x and y respectively:

Hence; one solution is:
`-2(-4)-2(0)=8`
