Sovle the equation for x0.5x-4=12
Amanda [17]

Value of x is x=32

Step-by-step explanation:

We need to find the value of x of the equation 0.5x-4=12

Solving the equation and finding value of x

0.5x-4=12\\

Adding 4 on both sides

0.5x-4+4=12+4\\0.5x=16\\

Divide both sides by 0.5

\frac{0.5x}{0.5} =\frac{16}{0.5}\\ x=32

So, value of x is x=32
