Solving an inequality when there is a variable on both

The video tutorial explains how to solve equations with variables on both sides. The teacher emphasizes the importance of isolating the variable and suggests eliminating the smaller variable to avoid negative numbers. The process involves subtracting like terms and simplifying the equation to find the solution. The tutorial concludes with a demonstration of solving a two-step equation.

What is the first step in solving an equation to isolate the variable X?

• Combine like terms

• Add a constant to both sides

• Divide both sides by a number

• Multiply both sides by a number

When dealing with variables on both sides of an equation, what is a recommended strategy?

• Add the variables together

• Eliminate the larger variable

• Eliminate the smaller variable

• Multiply the variables

Why is it beneficial to eliminate the smaller variable in an equation?

• To make the equation longer

• To avoid negative numbers

• To increase the number of variables

• To make the equation more complex

What operation is performed after subtracting to solve the two-step equation?

• Multiplication

• Subtraction

• Division

• Addition

What is the final solution for X in the given equation?

• X is not equal to 21

• X is greater than 21

• X is equal to 21

• X is less than 21
