Question

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

Answer 1

Step-by-step explanation:

5x - 6y = 30_________________eq.1

5x + 4y= 20__________________eq.2

subtract eq.2 from eq.1

5x-6y=30

5x+4y=20

---------------------

2y=10

y =5 _______________divided by 2

put the value of y in eq. in 2

5x+4y=20

5x+(4×5)=20

5x+20=20

5x=20-20

5x=0

x=0/5

x=0

hen's value of x =0

& value of y =5
