Answer:
x = 16
Explanation:
Write the equation
(8x + 4) + (3x) = 180
Remove the parentheses
8x + 4 + 3x = 180
Collect like terms
11x + 4 = 180
Move the constant to the right hand side and change its sign
11x = 180 - 4
Subtract
11x = 176
Divide both sides of the equation by 11 to get your final answer
x = 16
