Question
Solve the following equation:ln(𝑥+1)+ln(2𝑥−3)=ln(2)+ln(3𝑥−4)𝑥=
Solution
Sure, let's solve the equation step by step.
Given equation is: ln(𝑥+1) + ln(2𝑥−3) = ln(2) + ln(3𝑥−4)
Step 1: Use the property of logarithms, ln(a) + ln(b) = ln(a*b), to combine the logarithms on both sides of the equation.
This gives us: ln[(𝑥+1)(2𝑥−3)] = ln[2(3𝑥−4)]
Step 2: If ln(a) = ln(b), then a = b. So, we can remove the natural logarithm (ln) from both sides.
This gives us: (𝑥+1)(2𝑥−3) = 2(3𝑥−4)
Step 3: Expand both sides of the equation.
This gives us: 2x^2 - 3x + 2x - 3 = 6x - 8
Step 4: Simplify both sides of the equation.
This gives us: 2x^2 - x - 3 = 6x - 8
Step 5: Rearrange the equation to set it equal to zero.
This gives us: 2x^2 - 7x + 5 = 0
Step 6: Factor the quadratic equation.
This gives us: (2x - 5)(x - 1) = 0
Step 7: Set each factor equal to zero and solve for x.
This gives us: 2x - 5 = 0 and x - 1 = 0
Solving these gives us: x = 5/2 and x = 1
So, the solutions to the equation are x = 5/2 and x = 1.
