Q22 Solve the following equations :
(i) log (2x + 3) = log 7
(ii) log (x +1) + log (x - 1) = log 24
(iii) log (10x + 5) - log (x - 4) = 2
(iv) log105 + log10(5x+1) = log10(x + 5) + 1
(v) log (4y - 3) = log (2y + 1) - log3
(vi) log10(x + 2) + log10(x - 2) = log103 + 31og104.
(vii) log(3x + 2) + log(3x - 2) = 5 log 2.
