Answer:
a
Step-by-step explanation:
right on edge
6 < –3x < 5
–2 > x > –5/3
a.The student should have added 4 to all parts (left, middle, and right) to get 6 < –3x < 9.
b.The student divided 6/–3 incorrectly.
c.The student should not have switched the direction of the sign in the final step.
The second step is wrong because he did not add 4 to the number 5. Then the correct option is A.
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The solution to inequality is given below.
Step 1 ⇒ 2 < –3x –4 < 5
Step 2 ⇒ 6 < –3x < 5
Step 3 ⇒ –2 > x > –5/3
The student should have added 4 to all parts (left, middle, and right) to get 6 < –3x < 9.
The second step is wrong because he did not add 4 to the number 5. Then the correct option is A.
