Explain how to solve linear equations intwo varibles.
we are telling you the substitution method to solve the pair of linear equation because it will be easy to solve
STEP 1: Obtain the two equations .let the equations be
a1x + b1y + c1= 0 …………(1)
a2x + b2y + c2= 0 …………(2)
STEP 2: choose either of the two equations , say (1) and find the value of 1 variable, say y , in terms of the other i.e.x
STEP 3: substitute the value of y, obtained in step 2 , in the other equation i.e.(2)to get an equation in x
STEP 4: solve the equation obtained in step 3 to get the value of x
STEP 5: substitute the value of x obtained in step 4 in the expression for y in terms of x obtained in step 2 to get the value of y
Step 6 : the values of x and y obtained in step 4 and 5 respectively constitute the soln of the given system of two linear equation
