Question

If p/q=5/7 and p-q = -2, find the value of p + q.​

Answer 1

Step-by-step explanation:

answer is p+q is 5 +7= 12

Answer 2

Answer:

p + q = 12

Step-by-step explanation:

Given:

$\frac{p}{q} = \frac{5}{7}$

Here, p-q = -2

Here, $\frac{p}{q} = \frac{5}{7} \\ \\ = > p = \frac{5q}{7}$

Now, put the value of p in eq. (1),

$= > \frac{5q}{7} - q = - 2 \\ \\ = > \frac{5q - 7q}{7} = - 2 \\ \\ = > - 2q = - 2 \times 7 \\ \\ = > q = \frac{ 14}{2} \\ \\ = > q = 7$

Now, put the value of q in eq.(1),

=> p-7=-2

=>p=-2+7

=> p=5

therefore ,

=>p+ q = 5+7=12

=> p + q = 12
