If 4+3x≤6+x and 3x+5>2+2x; then x can take which of the following values?
- A2
- B-2
- C4
- D-4
Solution & Step-by-step Explanation
Let's solve both linear inequalities step by step:
First Inequality:
4+3x≤6+x
Subtract x from both sides:
4+2x≤6
Subtract 4 from both sides:
2x≤2
x≤1
Second Inequality:
3x+5>2+2x
Subtract 2x from both sides:
x+5>2
Subtract 5 from both sides:
x>−3
Combining both results, the range for x is:
−3Now let's check the given options to see which value falls inside this interval (−3,1]:
A) 2 (False, since 2>1)
B) −2 (True, since −3<−2≤1)
C) 4 (False, since 4>1)
D) −4 (False, since −4<−3)
Thus, x can take the value −2.
First Inequality:
4+3x≤6+x
Subtract x from both sides:
4+2x≤6
Subtract 4 from both sides:
2x≤2
x≤1
Second Inequality:
3x+5>2+2x
Subtract 2x from both sides:
x+5>2
Subtract 5 from both sides:
