There's no answer, because that's not a question. It's just an expression that
stands for a number. There's no way to know what number it is until you know
what numbers 'x' and 'y' are. And as soon as either of them changes, the value
of the whole expression changes.

There can be no answer because the question contains an expression, not an equation or inequality.
If you mean: -5x+6y = 30 then y = 5/6x+5 as a straight line equation
6y + (2-2)y = 6y 6(5) + (2-2)5 = 6(5) 30 + 0 = 30
Steps: y - 7y + 6 = 30 -6y + 6 = 30 -6y + 6 - 6 = 30 - 6 -6y = 24 -6y / -6 = 24 / -6 y = -4 Check work: -4 - 7(-4) + 6 = 30 -4 - (-28) + 6 = 30 -4 + 28 + 6 = 30 24 + 6 = 30 30 = 30
