Solve {l}{l/y=3x+4}{text{Solvefor}mtext{where}}{m=operatorname{A}(5,-1)}

$$\left. \begin{array} { l } { l / y = 3 x + 4 }\\ { \text{Solve for } m \text{ where} } \\ { m = \operatorname{A}(5, -1) } \end{array} \right.$$

Solve for x

$$x=\frac{l}{3y}-\frac{4}{3}$$

$$y\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by y.

$$l=3xy+y\times 4$$

Swap sides so that all variable terms are on the left hand side.

$$3xy+y\times 4=l$$

Subtract y\times 4 from both sides.

$$3xy=l-y\times 4$$

Multiply -1 and 4 to get -4.

$$3xy=l-4y$$

The equation is in standard form.

$$3yx=l-4y$$

Divide both sides by 3y.

$$\frac{3yx}{3y}=\frac{l-4y}{3y}$$

Dividing by 3y undoes the multiplication by 3y.

$$x=\frac{l-4y}{3y}$$

Divide -4y+l by 3y.

$$x=\frac{l}{3y}-\frac{4}{3}$$
