Question

Solve the following equations by Cramer's method:
5x - 6y + 30 = 0 and 5x + 4y - 20 = 0 (plzz only in Cramer's method)​

Answer 1

Answer:

5x -6y = -30; 5x +4y = 20 is x= 0 , y= 5.

Step-by-step explanation:

Solution: Let's first write the equations in proper way.

5x - y = -30 : 5x + 4y = 20

Following are the ordered pairs.

5x - 6y = -30 (-3, 25) (0, 5) (-6, 0)

5x + 4y = 20 : (2, 2.5) (5, -1.25) (0, 5)

Each point on the graph satisfies the equation

The two lines intersect each other at (0,5).
