Solve -1-(m-1)+m=m-1/2

$$- 1 - ( m - 1 ) + m = m - \frac { 1 } { 2 }$$

Solve for m

$$m=\frac{1}{2}=0.5$$

Steps for Solving Linear Equation

To find the opposite of m-1, find the opposite of each term.

$$-1-m-\left(-1\right)+m=m-\frac{1}{2}$$

The opposite of -1 is 1.

$$-1-m+1+m=m-\frac{1}{2}$$

Add -1 and 1 to get 0.

$$-m+m=m-\frac{1}{2}$$

Combine -m and m to get 0.

$$0=m-\frac{1}{2}$$

Swap sides so that all variable terms are on the left hand side.

$$m-\frac{1}{2}=0$$

Add \frac{1}{2} to both sides. Anything plus zero gives itself.

$$m=\frac{1}{2}$$
