Answer:
-8x + 146
Step-by-step explanation:
Step 1: Write out expression
3(58 - 6) - 2(4x + 5)
Step 2: Parenthesis
3(52) - 2(4x + 5)
Step 3: Multiply
156 - 2(4x + 5)
Step 4: Distribute
156 - 8x - 10
Step 5: Combine like terms (constants)
-8x + 146
First you would take 312 and divide it by 13. Using that answer and put it over 1. Then times the answer that you just got by twelve. Then put that in a mixed number in its simplest form.
