A linear equation represents a straight line.Thus, the solution of the system of linear equation depends on whether the lines intersect, not intersect or same line.
We have below cases:-
- The lines are non parallel and intersect at exactly one point. In this case we have one solution.
- The lines are parallel and hence never intersect. There is no solution in this case.
- The two lines represents the same line. Hence, infinitely many solutions.
We never got exactly two solutions because two lines can intersect at a single point.
52 ten cent coins, and you have 36 five cent coins.
Their sum is 700 cents which is equal to 7 dollars.
Simply plug g and h into the equation:
g + h =
(-7) + (3) = -4
