it would simply still be
7x+8y
You must have "like terms" to add variables meaning they both must be x or y . so your answer would still be 7x+8y

2x = -7 - 8y
It's just a mathematical polynomial: 7x + 3y.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
