Question

If p : q = 5 : 7 and p + q = –4 then what is value of ( 3p + 2p)​

Answer 1

answer

Step-by-step explanation:

Also, p-q=-4 or, 5k-7k=-4 or, -2k=-4 or, k=-4-2=2. ∴P=5k=5×2=10 and q=7k=7×2=14. ∴3p+4q=3×10+4×14=30+56=86.

Answer 2

5x + 7x = -4

12x = -4

x = -4/12

x= -1/3

p= -5/3

q= -7/3
