Answer:

1  \frac{5}{8}  \: is \: the \: answer..... \\

Step-by-step explanation:

7 - 3m + 2 - 5m =  - 4 \\  or \:  \:  \:  9 - 8m = - 4 \\ or \:  \:  \:  - 8m =  - 4 - 9 \\ or \:  \:  \:  - 8m =  - 13 \\ or \:  \:  \: m =  \frac{ - 13}{ - 8}  \\ or \:  \:  \: m =  \frac{13}{8}  \\ so \:  \:  \: m = 1 \frac{5}{8}  \\ then \:  \:  \:  \: 7 - 3( \frac{13}{8}) + 2 - 5( \frac{13}{8}) \\ so \:  \:  \: 7 -  \frac{39}{8}  + 2 -  \frac{65}{8} =  - 4 \\  so \:  \:  \:  \:  \frac{56 - 39}{8} +  \frac{16 - 65}{8} =  - 4 \\ so \:  \:  \:  \:  \frac{17}{8} +  \frac{ - 49}{8} =  - 4 \\ so \:  \:  \:  \:  \frac{17 - 49}{8} =  - 4 \\ so \:  \:  \:  \:  \frac{ - 32}{8} =  - 4 \\ so \:  \:  \:  \:  - 4 =  - 4(verified) \\
