Question

solve p + q = ¼ and 5p + 2q = 2 using elimination method​

Answer 1

Answer:

Step-by-step explanation:

5p + 2q = 2

p + q = 1/4 (multiply by -2)

  -2p - 2q = -1/2

   5p + 2q = 2

______________

3p + 0 =2 - 1/2

3p = 4 -1 /2

3p * 2 = 3

6p = 3

p = 3/6

p = 1/2

p + q = 1/4

1/2 + q = 1/4

q = 1/4 - 1/2  (lcm =4)

q = 1-2/4

q = -1/4
