Linear Equations in two Variables If the equation has more than one variable and the highest power of variable, appearing in the equation is 1, such that variables are not multiplied each other then this type of equation is known as “linear equation in two variable”. Some examples of linear equations in two variables are,       […]

Simultaneous equations by Elimination Method Steps for solve linear equations with elimination method. Step 1: First we arrange both equations in standard form, placing like variables and constants one above the other. Step 2: Choose a variable (x or y) to eliminate, Multiply both equations by a suitable(non zero) constant to make the coefficients of one […]

Angle Formed By Two Lines and a Transversal  In above figure line l, intersects two lines m and n at the point p and q respectively. Therefore, line l is a “Transversal” for lines m and n. Four angles are formed at the points p, by line l, name of these angles as  ∠1, ∠2, ∠3, and ∠4. Four angles are formed […]
