what is the mistake in this problem?

Asked by monyod

Answer (2)

You didn't multiply the 3 by 4 on step number 3. Your new problem should have been -4x +12=x + 4. You then move the variable term by adding 4x to each side. Your new problem is 12=5x + 4. Then, remove the constant by subtracting 4 on each side. Your new problem is 8=5x. Your answer is x=1 3/5 or 1.6

The mistake in the problem likely lies in the combination of like terms or arithmetical errors while moving terms across the equation. By following the steps to combine terms properly and checking the solutions through substitution, we can find the correct result. Always verify your calculations in each part of the problem to avoid errors.
