Question

5p+q=20 4p+5q=37 Plz solve this

Answer 1

Answer:

p = 3

q = 5

Step-by-step explanation:

5 p + q = 20 ------------------------------ 1

4 p + 5 q = 37-----------------------------2

from eq 1

q = 20 - 5 p -------------------------------3

put this value in eq 2

4 p + 5 ( 20 - 5 p ) = 37

4 p + 100 - 25 p =37

- 21 p = - 63

p = 3

put this value in eq 3

q = 20 - 5 p

q = 20 - 15

q = 5

Answer 2

Hey mate

Here is your answer to the question

5 p + q = 20 ------------------------------ 1

4 p + 5 q = 37-----------------------------2

from eq 1

q = 20 - 5 p -------------------------------3

put this value in eq 2

4 p + 5 ( 20 - 5 p ) = 37

4 p + 100 - 25 p =37

- 21 p = - 63

p = 3

put this value in eq 3

q = 20 - 5 p

q = 20 - 15

q = 5

So

p = 3 and q = 5
