Question

solve 7/3 = x/7 ?

Answer 1

49/3

Answer 2

how did you solve that ?

Answer 3

reverse the equality in 7/3 = x/7, in order to isolate the x to the left hand side:
7/3=x/7 is equivalent to x/7=7/3:
x/7=7/3

solve for x:
Multiply both sides by
7x/7=7*7/3

express 7*7/3 as a single fraction
7x/7 = 7*7/3

cancel common terms in the numerator and denomenator of 7x/7:
x= 7*7/3

multiply 7 and 7 together
7*7=49

answer:
x= 49/3
