Answer:
x = 50
Explanation:
to evaluate the question given to be x+2•x+30=180 we first of all combine the likely variables and evaluate.
solution
x+2•x+30=180
x + 2x + 30 = 180
x + 2x = 180 -30
3x = 150
divide both sides by the coefficient of x which is 3
3x /3 = 150/3
x = 50.
to check if your answer is correct put the value of x into the queston and evaluate carefully and you will observe that the left habdside is equal to the right handside.
