Question

Explain whether 13t−3t is equivalent to 3t−13t. Support your answer by evaluating the expressions for t=2.

Answer 1

They are not Equivalent.

Explanation:

You can tell that they aren't by doing that equations.

13t-3t=10t

3t-13t=-10t

If you were to inert 2 into t's , spot, it still would not work.

13(2)-3(2), 26-6=20

3(2)-13(2), 6-26=-20

Answer 2

• Not equivalent

Explanation:

• 13t - 3t = (13 - 3)t = 10t
• 3t - 13t = (3 - 13)t = -10t
• 10t ≠ -10t

They are not equivalent

When t = 2

• 13t - 3t = 13*2 - 3*2 = 26 - 6 = 20
• 3t - 13t = 3*2 - 13*2 = 6 - 26 = -20
