Solving Two-Step Equations| Math Defined with Mrs. C | 7.EE.B.4

This video tutorial covers solving algebraic equations that require two steps. It begins with an introduction to the concept and then provides detailed, step-by-step solutions to four different equations, including one with decimals. The tutorial emphasizes the importance of combining like terms and isolating the variable to find the solution. Each example demonstrates the process of moving constants and dividing to solve for the variable, ensuring a clear understanding of the method.

What is the first step in solving the equation -4P + 9 = -5?

• Add 9 to both sides

• Divide both sides by -4

• Subtract 9 from both sides

• Multiply both sides by -4

After moving the constant in the equation -6B - 7 = 17, what is the resulting equation?

• -6B = -10

• -6B = -24

• -6B = 24

• -6B = 10

In the equation 5 = -5Y, what operation is needed to solve for Y?

• Divide both sides by -5

• Multiply both sides by -5

• Subtract 5 from both sides

• Add 5 to both sides

What is the solution for Y in the equation 5 = -5Y?

• Y = 5

• Y = -5

• Y = 1

• Y = -1

What is the final solution for T in the equation -8.48 = -4.8T + 6.4?

• T = 31

• T = -3.1

• T = 3.1

• T = -31
