3(x-7)=5
3x - 21 = 5
3x = 21 + 5
x = 26/3
x = 8 2/3
David wanted to solve 3(x-7)=5. As a first step, he wrote 3x-21=15. What error did he make? Correct his error and then find the solution?
5 answers
Ok. so the error David make was putting 15 as the answerinstead of keep it as 5 correct?
Right.
Thank you Ms. Sue :))
