Someone please explain how this in general form 2x – 3y – 7 = 0 is 2x - 3y + 10 = 0​
Korvikt [17]

Answer:

Step-by-step explanation:

yes....the pair of linear equations has unique solution.....

2x + 3y - 7 = 0 ...... (i)

3x + 2y + 10 = 0 ....... (ii)

on comparing the equation i nd ii with a1x + b1y + c1 = 0

nd a2x + b2y + c2 = 0 reslectively......

a1 = 2 ; b1 = 3 ; c1 = -7

a2 = 3 ; b2 = 2 ; c2 = 10

here....its clear that......

a1 / a2 is not equal to b1 / b2

Therefore the given pair of linear equation have a unique solution........
