Question

p = 2q - 1 , q = 5 - 3p​

Answer 1

Step-by-step explanation:

Given

p= 2q -1, eq 1

q=5 - 3p eq 2

put 1 in 2

q= 5 - ( 2q -1)

= 5 - 2q +1

=6 - 2q

q + 2q = 6

3q = 6

q = 3

p=2q -1

= 4 - 1

p = 3

Answer 2

p = 2q - 1

We know that q = 5 - 3p
So ,
p = 2( 5 - 3p)
p = 10 - 6 p
p + 6p = 10
7p = 10
p = 10/7 //

q = 5-3p

We know that p = 10/7
So,
q = 5 - 3 x 10/7
q = 5 -30/7
q = 35 - 30 / 7
q = 5/7 //
