Question

3p - 5q = 7
4p + 5q = -14

please solve this simultaneous equation .

Answer 1

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.
