Recognize Equation Involves Logarithms: First, we need to recognize that the equation involves logarithms and exponents. We will start by simplifying the logarithmic part of the equation.log3(7−2x)=5(4x+11)Using the property of logarithms that logab=b⋅loga, we can simplify the left side of the equation:(7−2x)⋅log3=5(4x+11)
Simplify Left Side of Equation: Next, we need to deal with the right side of the equation. Since there is no simple way to convert 54x+11 to a base of 3 or to a logarithmic form that would easily allow us to solve for x, we will need to use a different strategy. We can apply logarithms to both sides of the equation to bring the exponents down. We will use the natural logarithm (ln) for this purpose:ln((7−2x)⋅log3)=ln(54x+11)
Apply Natural Logarithm: We apply the natural logarithm to both sides of the equation to bring down the exponents:ln(37−2x)=ln(54x+11)Using the property of logarithms that ln(ab)=b⋅ln(a), we can simplify both sides:(7−2x)⋅ln(3)=(4x+11)⋅ln(5)
Simplify Linear Equation: Now we have a linear equation in terms of x that we can solve. We will distribute ln(3) and ln(5) on both sides:7×ln(3)−2x×ln(3)=4x×ln(5)+11×ln(5)
Collect Like Terms: Next, we will collect like terms and move all terms involving x to one side of the equation and constants to the other side: −2x⋅ln(3)−4x⋅ln(5)=11⋅ln(5)−7⋅ln(3)
Factor Out x: We can factor out x from the left side of the equation:x⋅(−2⋅ln(3)−4⋅ln(5))=11⋅ln(5)−7⋅ln(3)
Divide to Solve for x: Now we will divide both sides by (−2×ln(3)−4×ln(5)) to solve for x:x=−2×ln(3)−4×ln(5)11×ln(5)−7×ln(3)
Calculate x Value: Finally, we can calculate the value of x using the values of ln(3) and ln(5):x=−2⋅ln(3)−4⋅ln(5)11⋅ln(5)−7⋅ln(3)
