Answer:
add x
Step-by-step explanation:
The operation "subtract 5" has eliminated the constant from the right side of the equation, so the next step would be to eliminate the variable from the left side. You do that by adding the opposite of the variable term.
The opposite of the term -x is x, so we "add x" as the next step.
This makes the solution look like ...
-x +6 = 5 -3x
-x +1 = -3x . . . . . . subtract 5
1 = -2x . . . . . . . . . add x
-1/2 = x . . . . . . . . .divide by -2

<em>Comment on this solution</em>
My preference is always to add the opposite of the variable term with the smallest coefficient. Here, that term is -3x, so I would add 3x as a first step. This leaves the only x-term with a <em>positive</em> coefficient, so can reduce errors in the solution.
Answer:
5.7
Step-by-step explanation:
the square root of 33 is 5.744562
the second unit to the right of the decimal is less than 5
therefore, you'd round down
