Answer: 138
Step-by-step explanation:
You’re going to solve this problem using PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction)
We have parentheses so we’re going to solve everything in there first. You will do division before subtraction.
20/4 = 5
Then subtract 28 - 5 = 23
You’re left with 6 x 23 = 138
