We are given that a + b = -7
and b = 10
Therefore a +10 = =7
Subtract 10 from each side
So a + 10 - 10 = -7 + 10
Which simplifiesn to a = 10 - 7
So a = 3

If I am correct, 9 plus 7 equals 112.
If: A+7 = -3 then A = -10
9 plus 7 equals 144. Generally, x plus y = x(x+y).
144 is the answer.2+3=10 which means 2+3=55*2=107+2=63 7+2=99*7=63now 9+7=? 9+7=1616*9=144

-7 plus 10 is the same as 10 minus 7, which is 3.
144 (square the first value and add the product of the two values). In the statement 7 + 6 should = 91, not 63, which would be 7 + 2.

16t plus 7 equals 19t plus 10. 16t+7=19t+10. Subtract 16t and 10 from both sides. -3=3t -1=t
