Answer:Tre made an error when adding or subtracting.
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.
