Solve x+4left(x+3right)=3x-8^2

$$x+4 \left( x+3 \right) = 3x- { 8 }^{ 2 }$$

Solve for x

$$x=-38$$

Steps for Solving Linear Equation

Use the distributive property to multiply 4 by x+3.

$$x+4x+12=3x-8^{2}$$

Combine x and 4x to get 5x.

$$5x+12=3x-8^{2}$$

Calculate 8 to the power of 2 and get 64.

$$5x+12=3x-64$$

Subtract 3x from both sides.

$$5x+12-3x=-64$$

Combine 5x and -3x to get 2x.

$$2x+12=-64$$

Subtract 12 from both sides.

$$2x=-64-12$$

Subtract 12 from -64 to get -76.

$$2x=-76$$

Divide both sides by 2.

$$x=\frac{-76}{2}$$

Divide -76 by 2 to get -38.

$$x=-38$$
