Solving Word Problems with 1-Step Equations

The video tutorial guides students through applying math to real-life problems, focusing on solving word problems using algebra. It covers defining variables, writing equations, and solving them step-by-step. The tutorial emphasizes understanding the problem context and ensuring solutions make sense. Students are encouraged to practice and verify their answers.

Why is it important to define a variable in algebra?

• It is a requirement by the teacher.

• It helps in solving the problem faster.

• It makes the equation look complex.

• It helps in understanding the problem better.

What is the first step in solving a word problem in algebra?

• Graphing the equation.

• Cutting along the dotted line.

• Defining a variable.

• Writing the solution in a sentence.

How do you form the equation from the word problem about Krista saving for a tablet?

• 35 + X = 70

• X + 35 = 70

• 35 - X = 70

• X - 35 = 70

What is the next step after forming the equation 35 + X = 70?

• Multiplying both sides by 35.

• Adding 35 to both sides.

• Isolating the variable X.

• Graphing the equation.
