Step-by-step explanation:
Answer:
A
Step-by-step explanation:
-
(x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )
- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1
- x - 3 > 2x - 6 ( subtract 2x from both sides )
- 3x - 3 > - 6 ( add 3 to both sides )
- 3x > - 3
divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity
x < 1
Answer:

Step-by-step explanation:
We are given the Inequality:

First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.
Simply, division!

2 divides 2 is 1; 2 divides 10 is 5.

Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.
Simplify the expression:-

Therefore, the value of y is less than 5.
