Question

Помогите!Решить:
1)p+2g/ 3p-g - 5g-2p/ g-3p
2)4- 3a/ 5-2b + 5(a-10)/ 2b-5

Answer 1

1) $\frac{p+2g }{3p-g} - \frac{ 5g-2p}{g-3p} = \frac{p+2g }{3p-g} + \frac{ 5g-2p}{3p-g} = \frac{p+2g+5g-2p }{3p-g} = \frac{7g-p }{3p-g}$

2) $\frac{4- 3a}{5-2b } + \frac{5(a-10)}{2b-5} = \frac{4- 3a}{5-2b } - \frac{5a-50}{5-2b} = \frac{4- 3a-5a+50 }{5-2b} = \frac{54-8a }{5-2b}$
