Question

4x + 1 + 9x -3 = 180

Answer 1

x = 14

Explanation:

4x + 1 + 9x -3 = 180

13x + 1 - 3 = 180

13x -2 = 180

13x = 180 + 2

13x = 182

x = 182 : 13

x = 14

---------------------------

check

4 × 14 + 1 + 9 × 14 - 3 = 180 (remember PEMDAS)

56 + 1 + 126 - 3 = 180

180 = 180

the answer is good
