Answer:
4x+3
How: -2x - (-6x) = 4
3 cannot be added there you go
Answer:
x < 6
Step-by-step explanation:
Given
3x - 6 < 12 ( add 6 to both sides )
3x < 18 ( divide both sides by 3 )
x < 6
Sandi did not follow PEMDAS. She added before multiplying and dividing. Her answer should be 18 because 6 • 4 = 24, 2 / 2 = 1, 24 + 1 = 25, 25 - 7 = 18
