TOPIC: similtaneous linear equations

p1 + 2q = 3,
p - 2q = 3

p = 3 ; q = 0

Step-by-step explanation:

In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that

& also . So, we can also equate them as :-

(∵ Both the eqn. have 3 in their right hand side product )

Solving the eqn. gives,

Putting the value of q in any one of the linear eqn gives ,

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
