how do you figure out this answer.15.6+xforx=-17.9

15.6 + x =-17.9

x = -17.9 + (-15.6)
x = -33.5

To figure out the answer for 15.6 + x when x = -17.9, you can substitute the value of x into the equation and solve for the variable.

Given the equation: 15.6 + x = -17.9

To isolate the variable x, we need to get rid of the constant on the left side of the equation. We can do this by subtracting 15.6 from both sides:

15.6 + x - 15.6 = -17.9 - 15.6

Simplifying the equation:

x = -33.5

Therefore, when x = -17.9, 15.6 + x is equal to -33.5.
