Solve 0.91x+0.95(4-x)=3.72

$$0.91 x + 0.95 ( 4 - x ) = 3.72$$

Solve for x

$$x=2$$

Steps for Solving Linear Equation

Use the distributive property to multiply 0.95 by 4-x.

$$0.91x+3.8-0.95x=3.72$$

Combine 0.91x and -0.95x to get -0.04x.

$$-0.04x+3.8=3.72$$

Subtract 3.8 from both sides.

$$-0.04x=3.72-3.8$$

Subtract 3.8 from 3.72 to get -0.08.

$$-0.04x=-0.08$$

Divide both sides by -0.04.

$$x=\frac{-0.08}{-0.04}$$

Expand \frac{-0.08}{-0.04} by multiplying both numerator and the denominator by 100.

$$x=\frac{-8}{-4}$$

Divide -8 by -4 to get 2.

$$x=2$$
