Solve the following equations: log (2x + 3) = log 7

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.
