ACT PREP - Solving for X with 2 Variables

The video tutorial guides viewers through solving a math problem involving two equations. It begins with setting up the problem and isolating the variable Y in two different equations. The tutorial then equates these expressions to solve for X, demonstrating the process of handling fractions and simplifying equations. The final solution is presented, with X equaling 2, and the tutorial concludes with a brief recap.

What is the first step in isolating the variable y in the equation 2x = 4 - y?

• Subtract 2x from both sides

• Add 2x to both sides

• Subtract 4 from both sides

• Add y to both sides

After isolating y in the equation 5y = 6 - 3x, what is the next step?

• Add 3x to both sides

• Multiply both sides by 5

• Divide both sides by 5

• Subtract 6 from both sides

What is the purpose of setting the two expressions for y equal to each other?

• To eliminate the variable x

• To solve for x

• To find the value of y

• To simplify the equation

How do you eliminate the fraction in the equation 6 - 3x/5 = 4 - 2x?

• Multiply both sides by 5

• Subtract 5 from both sides

• Add 5 to both sides

• Divide both sides by 5

What is the final value of x after solving the equation?

• x = 1

• x = 2

• x = 4

• x = 3
