Question

If x=2, y=3 is a solution of a pair of
lines 2x - 3y +a =0and 2x + 3y -b+2 = 0
then
​

Answer 1

Answer:

a=5 amd b=15

Step-by-step explanation:

since x=2, y=3 is a solution of a pair of of the given equation

$= > 2x - 3y + a = 0 \\ = > 2 \times 2 - 3 \times 3 + a = 0 \\ = > 4 - 9 + a = 0 \\ = > a = 5 \\ \\ = > 2x + 3y - b + 2 = 0 \\ = > 2 \times 2 + 3 \times 3 - b + 2 = 0 \\ = > 4 + 9 - b + 2 = 0 \\ = > 15 - b = 0 \\ = > b = 15$
