Solve 4.5k+b=3.5

$$4.5 k + b = 3.5$$

Solve for k

$$k=\frac{7-2b}{9}$$

Steps for Solving Linear Equation

Subtract b from both sides.

$$4.5k=3.5-b$$

Divide both sides of the equation by 4.5, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{4.5k}{4.5}=\frac{3.5-b}{4.5}$$

Dividing by 4.5 undoes the multiplication by 4.5.

$$k=\frac{3.5-b}{4.5}$$

Divide 3.5-b by 4.5 by multiplying 3.5-b by the reciprocal of 4.5.

$$k=\frac{7-2b}{9}$$

Solve for b

$$b=\frac{7-9k}{2}$$

Solution Steps

Subtract 4.5k from both sides.

$$b=3.5-4.5k$$
