Mathematics
1 answer:
Pavlova-9 [17]3 years ago
8 0

Answer:

it would be x=17 1/2

Step-by-step explanation:

i am going to go a little more into detail.

you would first have to divide each side to isolate the variable

x=5/2/7

simplifying steps:

you would have to change the 5 into 5/1

5/1÷2/7

now you have to keep the first number, change the sign, and then flip the last number, AKA KCF

5/1*7/2

35/2

and you can simplify this into a mixed number

17 1/2

hope this helps! have a nice day :)
