Marquis used the steps below to find the solution to the inequality Negative 5.6 greater-than-or-equal-to x + 3.6.
Step 1 Subtract 3.6 from both sides of the inequality.
Negative 5.6 greater-than-or-equal-to x + 3.6. Negative 5.6 minus 3.6 greater-than-or-equal-to x + 3.6 minus 3.6. Negative 9.2 greater-than-or-equal-to x.
Step 2 Interpret the results.
x greater-than-or-equal-to negative 9.2
x is greater than or equal to –9.2.
Step 3 Draw a number line.
A number line going from negative 9.5 to negative 8.8. A closed circle is at negative 9.2. Everything to the left of the circle is shaded.
Which describes the first step in which Marquis made an error?
