If a + b = 7 then our possible answers are 1 + 6, 2 + 5, or 3 + 4.

Now that we have the possible answers, we can times a and b to find 10.

1 • 6 = 6, 2 • 5 = 10, and 3 • 4 = 12.

So our answer is 2 + 5 = 7

2 and 5 being a and b.

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
