Question

Mrs. McAlister wrote the equation 10 t minus 4 t + 3 t = 8 on the board and asked students to write an equivalent equation. The table below shows the responses from four students.

Student Responses
Name
Equation
Michele
3 t = 8
Piotr
6 t = 8
Ronnie
Negative 1 t = 8
Tanisha
9 t = 8

Which student wrote an equation that is equivalent to Mrs. McAlister’s?

Answer 1

10t - 4t + 3t = 8
13t - 4t = 8 (will do addition first)
9t = 8
So, Tanisha’s equation will be equivalent
As Tanisha’s equation is :
9t = 8
