1. 3x -10=7x+14
2. Add 10 to both sides
3. 3x=7x+24
4. Subtract the variable ( 7x ) from both sides
5. -4x=24
6. Divide -4/24
I hope I did it right let me know if any errors
Answer:
13/14 is greater
Step-by-step explanation:
Find the lcm for both:
<u>9 x 7 </u> = <u>63</u>
10 x 7 70
<u>13 x 5 </u> = <u>65</u>
14 x 5 70
so therefore 13/14 is greater since it has a greater value when finding the lcm
