Answer:
x = 3
Step-by-step explanation:
5x + 3 = 3x + 9
subtract 3 on both sides (cancels out 3) (inverse operation)
5x = 3x + 6
subtract 3x on both sides (cancels out 3x) (inverse operation)
2x = 6
divide both sides by 2 (isolates x) (simplifies)
x = 3
Answer:
x < 2
Step-by-step explanation:
Given
5 + 2x < 9 ( subtract 5 from both sides )
2x < 4 ( divide both sides by 2 )
x < 2
