Solve -1x^-1+2+1/2*(-1)-3=0

$$-1 { x }^{ -1+2 } + \frac{ 1 }{ 2 } \times (-1)-3 = 0$$

Solve for x

$$x = -\frac{7}{2} = -3\frac{1}{2} = -3.5$$

Steps for Solving Linear Equation

Add -1 and 2 to get 1.

$$-x^{1}+\frac{1}{2}\left(-1\right)-3=0$$

Calculate x to the power of 1 and get x.

$$-x+\frac{1}{2}\left(-1\right)-3=0$$

Multiply \frac{1}{2} and -1 to get -\frac{1}{2}.

$$-x-\frac{1}{2}-3=0$$

Subtract 3 from -\frac{1}{2} to get -\frac{7}{2}.

$$-x-\frac{7}{2}=0$$

Add \frac{7}{2} to both sides. Anything plus zero gives itself.

$$-x=\frac{7}{2}$$

Multiply both sides by -1.

$$x=-\frac{7}{2}$$
