Pls help me to solve the following maths problem, thanks!

4m + 1/3 = 1 2/3 - 1/3m
4m * 3 + 1/3 * 3 = 5/3 * 3 - 1/3m * 3 …..(always get the LCM of the 分母 and multiply it to all)
12m + 1 = 5 - m
12m + m = 5 - 1
13m = 4
m = 4/13

- 你去消失左 d 分母之後, 條數就會易計好多架喇.(希望可以幫到你.)

- You always eliminate the denominators; then the calculation will be easier.(Hope can help you).

4 1/3m = 4/3
13/3m = 4/3
13m = 4
m = 4/13
