Solve 5*(-8)+9=x(-8)+8+3x+6

$$5 \times (-8)+9=x(-8)+8+3x+6$$

Solve for x

$$x=9$$

Steps for Solving Linear Equation

Multiply 5 and -8 to get -40.

$$-40+9=x\left(-8\right)+8+3x+6$$

Add -40 and 9 to get -31.

$$-31=x\left(-8\right)+8+3x+6$$

Combine x\left(-8\right) and 3x to get -5x.

$$-31=-5x+8+6$$

Add 8 and 6 to get 14.

$$-31=-5x+14$$

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

$$-5x+14=-31$$

Subtract 14 from both sides.

$$-5x=-31-14$$

Subtract 14 from -31 to get -45.

$$-5x=-45$$

Divide both sides by -5.

$$x=\frac{-45}{-5}$$

Divide -45 by -5 to get 9.

$$x=9$$
