Question

solve simultaneous equation graphically
5x-6y+30=0
5x+4y-20=0​

Answer 1

Answer:

5x-6y+30=0 ; 5x+4y-20=0 Solve the simultaneous equation...

Answer: x = 0 , y = 5.

Step-by-step explanation: 5x-6y+30=0 eq 1. 5x+4y-20=0 eq2. Equating both equations. 5x-6y+30 = 5x+4y-20. => 50 = 10y. => y = 5. 5x + 4*5 - 20 = 0. => 5x = 0. => x = 0. (0 , 5) x 5x-6y+30=0 5x+4y-20=0. -3 2.5 8.75. -2 10/3 7.5. -1 25/6 6.25.

0 5 5. 1 35/6 3.75. 2 20/3 2.5. 3 7.5 1.25.

Answer 2

Answer:

For 5x−6y+30=0:

x 0 -6 6

y  5 0 10

For x−y−1=0:

x  0 4 -4

y  5 0 10

As the graph shows, vertices of triangle are (0,5),(6,0)&(4,0).
