Question

cross multiplication method for system of equations

Answer 1

ax + by + c = 0, (a, b ≠ 0)  

Two such equations can be written as:  

a₁x + b₁y + c₁ = 0 ----------- (i)  

a₂x + b₂y + c₂ = 0 ----------- (ii)

Answer 2

hey sakna here

1.Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction. Let's say you're working with the equation 2/x = 10/13. Now, multiply 2 * 13. 2 * 13 = 26.

2.Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction. Now multiply x by 10. x * 10 = 10x. You can cross multiply in this direction first; it really doesn't matter as long as you multiply both numerators by the denominators diagonal from them
