X/10 + 2/5= -2/5 the solution is x=?

-8

Step-by-step explanation:

Find common denominators. Note that what you do to the denominator, you must do the the numerator.

x/10 + (2 * 2)/(5 * 2) = (-2 * 2)/(5 * 2)

x/10 + 4/10 = -4/10

Simplify. Isolate the variable, x.

x/10 + 4/10 (-4/10) = -4/10 (-4/10)

x/10 = -4/10 - 4/10

x/10 = -8/10

x = -8

x = -8 is your answer.
