Answer:
p = -1 and q = -2
Step-by-step explanation:
Given that:
3p-5q = 7
4p+5q = -14
To find:
p and q values.
Proof:
From given,
3p - 5q = 7
4p + 5q = -14
On adding both the equations, we have,
7p = -7
p = -1
On substituting p value in equation 1, we have,
3(-1) - 5q = 7
-3 - 5q = 7
-5q = 10
q = -2.
Therefore, the values of p and q are -1 and -2 respectively.
Hope it helps you.
Good Luck.
