Answer 1

Answer:

p=4a−4b−4c

p=4a−4b−4c</p><p>q=7a−7b−c

p=4a−4b−4c</p><p>q=7a−7b−c</p><p>2p+3q=2(4a−4b−4c)+3(7a−7b−c)

p=4a−4b−4c</p><p>q=7a−7b−c</p><p>2p+3q=2(4a−4b−4c)+3(7a−7b−c)</p><p>=8a−8b−8c+21a−21b−3c

p=4a−4b−4c</p><p>q=7a−7b−c</p><p>2p+3q=2(4a−4b−4c)+3(7a−7b−c)</p><p>=8a−8b−8c+21a−21b−3c</p><p>=29a−29b−11c
