Simplifying:
6x%2B%28x-3%29%2B%283x%2B7%29=180-->6x%2Bx-3%2B3x%2B7=180-->6x%2Bx%2B3x%2B7-3=180-->10x%2B4=180
because parentheses following a "+" sign do not change the meaning of an expression.
Solving:
10x%2B4=180-->10x%2B4-4=180-4-->10x=180-4-->10x=176-->10x%2F10=176%2F10-->x=176%2F10-->highlight%28x=17.6%29 or highlight%28x=88%2F5%29
