A system of linear equations:
A system of linear equations is a collection of one or more linear equations involving the same variables.
A system of linear equation has
- one solution when the graph intersect at a point.
- no solution when the graphs are parallel.
- infinitely many solutions when the graphs are exact same line.
According to the given questions
the given system of equations
(1). 2x+2y=3 and 4x+4y=6
if we see the graph of the above system of linear equations, the graphs are the" exact at same line".
Hence, they have infinitely many solution.
(2). 7x+5y=8 and 7x+7y =8
if we see the graph of the above system of linear equations, the graphs are intersecting at a single point.
Hence, there is only one solution.
(3). -2x+3y=7 and 2x-3y=-7
if we see the graph of the above system of linear equations, the graphs are exact at same line.
Hence, there is infinitely many solutions.
