Answer
$$x = 64$$
Work Step by Step
To solve this equation, we need to isolate the variable on one side of the equation and the constants on the other.
Distribute what is in parentheses first:
$$x = 360 - 4x - 40$$
Move the variable to one side of the equation by adding $4x$ to each side:
$$5x = 360 - 40$$
Simplify the right-hand side of the equation:
$$5x = 320$$
Isolate $x$ by dividing both sides of the equation by $5$:
$$x = 64$$
