Answer 1

Solve for x (get x by itself)

$4x-\frac{5}{y} =2z$       Add 5/y on both sides

$4x-\frac{5}{y}+\frac{5}{y}=2z+\frac{5}{y}$

$4x=2z+\frac{5}{y}$       Divide 4 on both sides to get "x" by itself

$\frac{4x}{4} =\frac{2z+\frac{5}{y}}{4}$

$x = \frac{z}{2}+\frac{5}{4y}$

If dividing 4 confuses you, then you can do this:

$4x=2z+\frac{5}{y}$      Multiply 1/4 on both sides

$(\frac{1}{4})4x=(2z+\frac{5}{y})(\frac{1}{4})$  Distribute 1/4 into (2z + 5/y)

$x=(2z(\frac{1}{4})+\frac{5}{y}(\frac{1}{4}))$

$x = \frac{z}{2} +\frac{5}{4y}$
