A

Step-by-step explanation:

Remark

Remember to read this over a little at a time.

Start with 3 times a number which is 3x Then go to the sum of 3 times a number and 8 which 3x + 8 Now read 9 * (3x + 8) The result is 180

9 * (3*x + 8) = 180 Remove the brackets

27x + 72 = 180 Subtract 72 from both sides.

27x = 180 - 72 Combine

27x = 108 Divide by 27

x = 108/27

x = 4 Answer
