The denominator is 15. So we amplify x/3 by 5, 1 by 15 and we leave the result as it is

5x+15=7
5x=7-15
5x=8
x=8/5
0
i need {the denominator is 15. So we amplify x/3 by 5, 1 by 15 and we leave the result as it is}in math signs and words

X/3+1=7/15
transpose 1 to rhs
x/3=7/15-1
x/3=7-15/15
x/3= -8/15
x= -8*3/15
x= -8*5
x = -40
0
please mark as the best
U R WRONG ANSWER IS -8/5
little correction in ur last two steps as follows
x/3+1=7/15
transpose 1 to rhs
x/3=7/15-1
x/3=7-15/15
x/3= -8/15
x= (-8/15)*3
x= -8/5
Hence the answer is x = - 8/5 !!!!
enjoy :)
