5x +3/5=3 is TRUE
where x= number
First find the value of the x
5x=3-3/5
(Find common denominator; which is 5)
5x=15/5-3/5
5x=12/5
then transpose 5 and divide it to 12/5
x= 12/5 /5
since you cannot divide fractions, you have to reciprocate the divisor which is 5 and then multiply. 5 becomes 1/5
x= 12/5 x 1/5
x= 12/25
Prove: 5x+3/5=3
5 (12/25) +3/5=3
(Find common denominator for both; which is 25)
60/25+3/5=3
60/25+15/25=3
75/25=3
3=3
