Question

Solve for z40=19+1/4z

Answer 1

To solve this equation for z, we can proceed as follows:

1. Subtract 19 from both sides of the equation:

`40-19=19-19+(1)/(4)z\Rightarrow21=(1)/(4)z`

2. Multiply by 4 to both sides of the equation (Multiplication property of equality):

`4\cdot21=4\cdot(1)/(4)z\Rightarrow84=(4)/(4)z\Rightarrow z=84`

Therefore, the value for z is equal to 84.
