Answer:
Step-by-step explanation:
3(4a + 6b) = 3*4a + 3*6b = 12a + 18b
-2(7a + b) = -2*7a + (-2)*b = -14a - 2b
![\frac{5[3(4a+6b)-2(7a+b)-b]}{20}=\frac{5[12a+18b-14a-2b-b]}{20}\\\\ \frac{5[-2a+15b]}{20}=\frac{15b-2a}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5B3%284a%2B6b%29-2%287a%2Bb%29-b%5D%7D%7B20%7D%3D%5Cfrac%7B5%5B12a%2B18b-14a-2b-b%5D%7D%7B20%7D%5C%5C%5C%5C%20%5Cfrac%7B5%5B-2a%2B15b%5D%7D%7B20%7D%3D%5Cfrac%7B15b-2a%7D%7B4%7D)
