Solve 18-(-x+5)=-10

$$18 - ( - x + 5 ) = - 10$$

Solve for x

$$x=-23$$

Steps for Solving Linear Equation

To find the opposite of -x+5, find the opposite of each term.

$$18-\left(-x\right)-5=-10$$

Subtract 5 from 18 to get 13.

$$13-\left(-x\right)=-10$$

Subtract 13 from both sides.

$$-\left(-x\right)=-10-13$$

Subtract 13 from -10 to get -23.

$$-\left(-x\right)=-23$$

Divide both sides by -1.

$$-x=\frac{-23}{-1}$$

Fraction \frac{-23}{-1} can be simplified to 23 by removing the negative sign from both the numerator and the denominator.

$$-x=23$$

Multiply both sides by -1.

$$x=-23$$
