Answer:
D
Step-by-step explanation:
Because the numbers do not comply with the like 11+6+18+21= no answer and multiplying them all didn't matter either so its none of the above
In the step after -6x+10=4x+20, he moved the terms incorrectly. you have to add 6x to both sides so it would be 10=4x+6x+20 which simplifies to 10=10x+20. subtract 20 from both sides to get -10=10x. divide both sides by 10. the answer is x=-1
