Answer:
solution is x=3
Step-by-step explanation:
apply log property
log a- log b= log a/b

Answer:
x < 5
Step-by-step explanation:
Step 1: Simplify
7x−35<2x−10
Step 2: Substract 2x from both sides
7x−35−2x<2x−10−2x
5x−35<−10
Step 3: Add 35 to both sides
5x−35+35<−10+35
5x<25
Step 4: Divide by 5
5x/5 × 25/5
x < 5
