Answer: no solutions/intersections
Step-by-step explanation:
1. Combine like terms
-3+4m=18+2m=15-2m
2. Combine like terms from the equal sign starting from the left
21-2m=15-2m
3. Combine like terms
21-2m= 12-2m
-15 +2m
6= 0
4. Since the values of m's cancel out because of the positive and negative you are left with no solution. This tells you that your equation is either true or false,
