Answer:
-2
Step-by-step explanation:
We assume you want to find the number. Let it be represented by x.
(6+2x)·5 = -3x +4 . . . . . the meaning of the problem statement
30 +10x = -3x +4 . . . . . eliminate parentheses
26 +13x = 0 . . . . . . . . . add 3x-4 to both sides
2 + x = 0 . . . . . . . . . . . . divide by 13
x = -2 . . . . . . . . . . . . . . subtract 2
The number is -2.
