Question

(d) Solve the following equations for respective
values of p and q.
2p + 5q = 20 and 5p + 69 = 37

Answer 1

Answer:

Hi friends

Step-by-step explanation:

5p+69=37

p=(37-69)/5

p=-32/5

2(-32/5)+5q=20

q=(20+64/5)/5

q=164/25

Answer 2

Step-by-step explanation:

5p + 69 = 37

5p = 37 - 69

5p = -32

p = -32/5

p = -6.4

now

2p + 5q = 20

by putting the value of p

2(-6.4) + 5q = 20

-12.8 + 5q = 20

5q = 32.8

q = 32.8/5

q = 6.56
