Bruno claims that the solution to the linear equation –3(2x + 6) + 25 = 1 is x = 1. He shows the steps below to justify his solution. Step 1:
Step 2:
Step 3:
Step 4:
-312x+6) + 28-1
-6 x - 18 +25 - 1
-6x + 7 = 1
-6 x = -6
x-1
Which of the following statements shows correct reasoning regarding the solution?
The solution is incorrect since Step 2 should be -6 - 43 = 1, so the correct solution is x = -7
The solution is correct since the solution x = 1 follows from the constant shown on the right side of the original equation
The solution is correct since the solution x = 1 follows from the equality of numbers asserted in each of the previous steps
The solution is incorrect since Step 1 should be -6 x + 18 + 25 = 1, so the correct solution is x = 7
