Answer:
step 2 is where she made her mistake
Step-by-step explanation:
- 4x + 1 > 9 ( subtract 1 from both sides )
- 4x > 8
divide both sides by - 4 , reversing the symbol as a result of dividing by a negative quantity.
x < - 2

Answer:
x−5=8
1 Let x=13x=13.
13-5=813−5=8
2 Simplify 13-513−5 to 88.
8=88=8
Represent 'a number' as x
18 less than (-18) the product of 33 and a number (product is multiplcation so 33 times x or 33x) is (=) 180 (180)
-18+33x=180
add 18 to both sides
33x=198
divide both sides by 33
x=6
