2. for which values of a and b does the following pair of linear equations have
infinite number of solutions?
2x + 3y=7
(a - b) x + (a + b) y = 3a + b 2
(ii) For which value of k will the following pair of linear equations have no solution?
3x + y = 1
(2k-1) x + (k-1)y=2k + 1

Answer:
An equation for a straight line is called a linear equation. The general representation of the straight-line equation is y=mx+b, where m is the slope of the line and b is the y-intercept. Linear equations are those equations that are of the first order. These equations are defined for lines in the coordinate system.
