Question

$$7x+9y=16.x=y=1.EXPLAIN$$

Solve for x

$x=\frac{16-9y}{7}$

Steps for Solving Linear Equation

Subtract $9y$ from both sides.

$$7x=16-9y$$

Divide both sides by $7$.

$$\frac{7x}{7}=\frac{16-9y}{7}$$

Dividing by $7$ undoes the multiplication by $7$.

$$x=\frac{16-9y}{7}$$

Solve for y

$y=\frac{16-7x}{9}$

Steps for Solving Linear Equation

Subtract $7x$ from both sides.

$$9y=16-7x$$

Divide both sides by $9$.

$$\frac{9y}{9}=\frac{16-7x}{9}$$

Dividing by $9$ undoes the multiplication by $9$.

$$y=\frac{16-7x}{9}$$
