Im pretty sure you can set the problems equal to each other but for solving real world problems if its a word problem find the main needed facts

Equations with the variable on both sides can be used to solve real-world problems by setting up an equation that represents the situation and then solving for the variable.

Equations with the variable on both sides can be used to solve real-world problems by setting up an equation that represents the situation and then solving for the variable. Here are the steps:

Identify the unknown variable and the known variables in the problem.

Write down the equation that represents the relationship between the known and unknown variables.

Simplify the equation by combining like terms and isolating the variable on one side of the equation.

Continue simplifying until the variable is alone on one side of the equation.

Solve for the variable by performing the inverse operations needed.

Check your solution by substituting the value of the variable back into the original equation to see if it satisfies the conditions of the problem.
