uysha [10]

Answer:Tre made an error when adding or subtracting.

Step-by-step explanation:

the solution to the equation 3.57x + 1.61 = 4.71 minus 2.63 x is x = 0.5.

He verifies his solution using the steps below. Equation:

3.57 x + 1.61 = 4.71 minus 2.63x

Step 1: 3.57 (0.5) + 1.61 = 4.71 minus 2.63 (0.5)

Step 2: 1.785 + 1.61 = 4.71 minus 1.315

Step 3: 3.395 = 6.025

Looking at step 2, 4.71 minus 1.315 = 3.395. This would make the left hand side of the equation and the right hand side of the equation to be the same. Therefore,

Tre made an error when adding or subtracting.
