This chapter discusses linear equation in two variables. Elementary algebra deals with equations such as 3 x = 5, x 2 y = 8, and x + 3 y 2 z = 14. These are classed as first-degree equations, also called linear equations, because their unknown quantities appear no more than once in...
Linear Equation In Two Variables Topic Covered : Graph and Condition for Solvability of L.E. Q1 :- Draw the Graphs of the given equations ; 2x – 3y + 6 = 0 ; 2x + 3y – 18 = 0 ; y -2 = 0 Find the vertices of the triangle so obtained. Also find the area of the triangle...
Substitute (4) in (2), 4x - y = 7 4(2) - y = 7 8 - y = 7 y = 1 Therefore, x = 2, y = 1 Similarly, you can try the linear equations in two variables calculator to solve the linear equation in two variables for: ...
