Solving two step equation with decimals

The video tutorial explains how to solve equations involving decimals. It begins by introducing the concept of using decimals in equations and emphasizes that the basic operations remain unchanged. The instructor sets up an example equation and demonstrates how to solve it using inverse operations. The process involves subtracting and dividing to isolate the variable. The tutorial concludes by verifying the solution and reinforcing the method's reliability.

What is the main point the teacher emphasizes about solving equations with decimals?

• Decimals make equations unsolvable without a calculator.

• Decimals should always be converted to fractions.

• Decimals do not change the fundamental approach to solving equations.

• Decimals require a completely different set of operations.

In the example equation 1.3 + 0.5 * X = -3.41, what is the first step to isolate X?

• Divide both sides by 0.5.

• Add 1.3 to both sides.

• Multiply both sides by 0.5.

• Subtract 1.3 from both sides.

After subtracting 1.3 from both sides, what is the resulting equation?

• 0.5 * X = 4.71

• X = -4.71

• X = 4.71

• 0.5 * X = -4.71

What is the equivalent operation to dividing by 0.5?

• Multiplying by 2

• Adding 0.5

• Multiplying by 0.5

• Dividing by 2

What is the final value of X in the equation 1.3 + 0.5 * X = -3.41?

• 4.71

• -9.42

• 9.42

• -4.71
