Answer:
Substitute the solution for x into either equation to find y. ... 4x + 6y = 9 ... Since the left side does not equal the right, there is no solution to this system of equations. ... 4x + y = 10. SOLUTION: y = 5x + 1. 4x + y = 10. Substitute 5x + 1 for y in the second equation. ... Graph each system and determine how many solutions it has.
Graphical solution. Example 1. given are the two following linear equations: f(x) = y = 1 + .5x. f(x) = y = 11 - 2x. Graph the first equation by finding two data points.
