Solve z=-1/2(3)+4

$$z = - \frac { 1 } { 2 } ( 3 ) + 4$$

Solve for z

$$z = \frac{5}{2} = 2\frac{1}{2} = 2.5$$

Steps for Solving Linear Equation

Express -\frac{1}{2}\times 3 as a single fraction.

$$z=\frac{-3}{2}+4$$

Fraction \frac{-3}{2} can be rewritten as -\frac{3}{2} by extracting the negative sign.

$$z=-\frac{3}{2}+4$$

Convert 4 to fraction \frac{8}{2}.

$$z=-\frac{3}{2}+\frac{8}{2}$$

Since -\frac{3}{2} and \frac{8}{2} have the same denominator, add them by adding their numerators.

$$z=\frac{-3+8}{2}$$

Add -3 and 8 to get 5.

$$z=\frac{5}{2}$$

Assign z

$$z≔\frac{5}{2}$$
