Answer 1

Answer:

BY DOING THIS YOU WILL BE ABLE TO SOLVE THE ANSWER

Step-by-step explanation:

Here we will discuss about simultaneous linear equations by using cross-multiplication method.

General form of a linear equation in two unknown quantities:  

ax + by + c = 0, (a, b ≠ 0)  

Two such equations can be written as:  

a₁x + b₁y + c₁ = 0 ----------- (i)  

a₂x + b₂y + c₂ = 0 ----------- (ii)  

Let us solve the two equations by the method of elimination, multiplying both sides of equation (i) by a₂ and both sides of equation (ii) by a₁, we get:  

a₁a₂x + b₁a₂y + c₁a₂ = 0

a₁ a₂x + a₁b₂y + a₁c₂ = 0

Subtracting, b₁a₂y - a₁b₂y + c₁a₂ - c₂a₁ = 0

or, y(b₁ a₂ - b₂a₁) = c₂a₁ - c₁a₂
