You cannot solve it with two unknown values 'x' & 'y' .

However, it can be rearranged to form a strasight line eq'n.

Hence

-3x -3y = -15

Cancel down by '3'

Hence

-x -y = -5

Multiply by '-1',

Hence

x + y = 5

Hence

y = -x + 5 Is the straight line eq'n.

It has a slope/gradient of '-1' ; the coefficient of 'x'

It intercepts the y-axis at '5'. ; ( 0,5)
