−3x − 42 >3 please solve this
2 answers:
x > -15
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
-3*x-42-(3)<0
Pull out like factors :
-3x - 45 = -3 • (x + 15)
Divide both sides by -3
Remember to flip the inequality sign:
Subtract 15 from both sides
x > -15
Answer:
x < - 15
Step-by-step explanation:
Given
- 3x - 42 > 3 ( add 42 to both sides )
- 3x > 45
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x < - 15

Answer:
x ≤ 2
Step-by-step explanation:
Given the inequality :
5 x − 6 ≤ 2 + ( 3 x − 4 )
Open The bracket
5x - 6 ≤ 2 + 3x - 4
Collect like terms
5x - 3x ≤ 2 - 4 + 6
2x ≤ 4
Dibide both sides by 2
2x /2 ≤ 4/ 2
x ≤ 2
