Please don't get mad at me but I did this on tn ready the other day and we learned about it but what you would do is multiply 8x9 then subtract 7 from the product and add 4 to the answer you got and then multiply it by that answer by 5 and you should get your answer. I hope I helped you?

you find the answer by first multiplying 8x9=72 then 4x5=20 and then 72-9=63 and then 63+4=67 your final answer should be 87
