the answer is y=4
OpenStudy (anonymous):
how did you get that??
OpenStudy (anonymous):
on the LHS
we have 3^4y/3^7-y
which i s 3^5y-7
on the rhs we have
3^4y+3/3^3y-6
which is 3^y+9
equating the powers on the 2 sides we get
y=4
jhonyy9 (jhonyy9):
like expoent will get 5y-7=y+9 from this you need calcule the y so 4y=16 so y=16/4 =4
y=4
jhonyy9 (jhonyy9):
like exponent wann to be - sorry
