u work backwards. u start with ur answer, -10. then u add 5 instead of subtracting. ur problem then becomes -10+5. the answer being -5.
working backwards is the simplest method of algebra.

If you need a proof, do this:
x-5=-10 Given
x-5+5=10+5 Addition Property of Equality
x=15 Simplification

How do you solve x - x x?

x10 = x5.x5 = (x5)2 [x power five whole squared] Equation is x10 + x5 - 2 Replacing x10 (x5)2+x5 - 2 Substituting x5 by Y Equation becomes Y2 + Y - 2 = 0 Y2 + 2Y - Y - 2 = 0 Y(Y + 2) - 1(Y+2) = 0 (Y-1)(Y+2) = 0 The values of Y are 1 and -2 Y = x5 = 1 Therefore, x = 1 Y = x5 = -2 x = fifth root of -2, which is an imaginary value.
