X+y = -7
70 + 2y = 6
x + y = -7
2y = -64
y = -32
x + -32 = -7
x = -7 + 32 = 25
25 and -32

asked 11/10/18The sum of two numbers is negative seven. The sum of twice the smaller number and seventy is six. Find both numbers? I got -32 for one but can’t seem to find the other number.

So you found one number to be -32. That should be the smaller number. Thus, the larger number would be 25.
Let x be the smaller number and y be the larger number.
x + y = -7
2x + 70 = 6 -> x = -32
-32 + y = -7 -> y = 25
