Question

2x-3y+6=0,
4x+5y+2=0
(by cross multiplication)​

Answer 1

Answer:

Consider the given set of equations

2x+3y+8=0

4x + 5y + 14 = 0

Let us consider the general set of equations:

a₁x+b₁y+C₁ = 0

a₂x + b₂y+c₂ = 0

By cross multiplication, we have,

X 1 O

Here,

a₁=2, b₁ = 3, and c₁ = 8

a2=4, b₂-5 and c₂ = 14

Thus,

X 3 x 14-5x8 4x8-2x 14 1 2x (5)-4x3

Thus,

X 3x14-5x84x82x14 1 2 x (5)-4x3 =

X 1 42-40-32-28-10-1 12

X 1 4

⇒ x = -1 and y = -2
