Question

write all formule of linear equations
(icse class 10 maths)​

Answer 1

Linear Equations

One Variable ax+b=0 a≠0 and a&b are real numbers

Two variable ax+by+c = 0 a≠0 & b≠0 and a,b & c are real numbers

Three Variable ax+by+cz+d=0 a≠0 , b≠0, c≠0 and a,b,c,d are real numbers

Pair of Linear Equations in two variables:

a1x+b1y+c1=0

a2x+b2y+c2=0

Where

a1, b1, c1, a2, b2, and c2 are all real numbers and

a12+b12 ≠ 0 & a22 + b22 ≠ 0
