Solve 40-80-3/4=2(u-3)

$$\frac { 40 - 80 - 3 } { 4 } = 2 ( u - 3 )$$

Solve for u

$$u = -\frac{19}{8} = -2\frac{3}{8} = -2.375$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 4.

$$40-80-3=8\left(u-3\right)$$

Subtract 80 from 40 to get -40.

$$-40-3=8\left(u-3\right)$$

Subtract 3 from -40 to get -43.

$$-43=8\left(u-3\right)$$

Use the distributive property to multiply 8 by u-3.

$$-43=8u-24$$

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

$$8u-24=-43$$

Add 24 to both sides.

$$8u=-43+24$$

Add -43 and 24 to get -19.

$$8u=-19$$

Divide both sides by 8.

$$u=\frac{-19}{8}$$

Fraction \frac{-19}{8} can be rewritten as -\frac{19}{8} by extracting the negative sign.

$$u=-\frac{19}{8}$$
