Write the number of solutions of the following pair of linear equations:
x+3y−4=0 and 2x+6y−7=0.
1st equation can be re-written as y= −x3+43
comparing with y=mx+c , m= −13
2nd equation can be written as
y= −x3+76
comparing with y=mx+c , m= −13
so slopes of both the lines are same. so they are parallel and never intersect.
so number of solutions for this pair of linear equations is zero
