Solve the literal equation for x: g= 4x+5xy

Andreas93 [3]

The literal equation for x is $\frac{g}{4+5y}$ given that $g= 4x+5xy$

The subject of a formula is a way of representing a variable in terms of other variables.

Given the equation

$g= 4x+5xy$

Factor out the common variable x

$g= x(4+5y)$

Divide both sides by 4+5y

$\frac{g}{4+5y} =\frac{x(4+5y)}{4+5y} \\\frac{g}{4+5y} = x\\Swap\\x = \frac{g}{4+5y}$

This shows that the literal equation for x is $\frac{g}{4+5y}$
