Solve 3151.2*A+727.2*B=155.3

$$3151.2 \times A + 727.2 \times B = 155.3$$

Solve for A

$$A=-\frac{3B}{13}+\frac{1553}{31512}$$

Steps for Solving Linear Equation

Subtract 727.2B from both sides.

$$3151.2A=155.3-727.2B$$

The equation is in standard form.

$$3151.2A=-\frac{3636B}{5}+155.3$$

Divide both sides of the equation by 3151.2, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{3151.2A}{3151.2}=\frac{-\frac{3636B}{5}+155.3}{3151.2}$$

Dividing by 3151.2 undoes the multiplication by 3151.2.

$$A=\frac{-\frac{3636B}{5}+155.3}{3151.2}$$

Divide 155.3-\frac{3636B}{5} by 3151.2 by multiplying 155.3-\frac{3636B}{5} by the reciprocal of 3151.2.

$$A=-\frac{3B}{13}+\frac{1553}{31512}$$

Solve for B

$$B=-\frac{13A}{3}+\frac{1553}{7272}$$

Steps for Solving Linear Equation

Subtract 3151.2A from both sides.

$$727.2B=155.3-3151.2A$$

The equation is in standard form.

$$727.2B=-\frac{15756A}{5}+155.3$$

Divide both sides of the equation by 727.2, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{727.2B}{727.2}=\frac{-\frac{15756A}{5}+155.3}{727.2}$$

Dividing by 727.2 undoes the multiplication by 727.2.

$$B=\frac{-\frac{15756A}{5}+155.3}{727.2}$$

Divide 155.3-\frac{15756A}{5} by 727.2 by multiplying 155.3-\frac{15756A}{5} by the reciprocal of 727.2.

$$B=-\frac{13A}{3}+\frac{1553}{7272}$$
