Question

solve the following simultaneous equations graphically 10class mathematics part-1 5x-6y+30= :5x+4y-20=0​

Answer 1

EXPLANATION.

• GIVEN

5x - 6y + 30 = 0 .....(1)

5x + 4y - 20 = 0 .....(2)

TO FIND VALUE OF X AND Y.

from equation (1) and (2)

multiply equation (1) by 4

multiply equation (2) by 6

we get,

20x - 24y + 120 = 0

30x + 24y - 120 = 0

we get,

50x = 0

x = 0

put x = 0 in equation (2)

we get,

5x + 4y - 20 = 0

5(0) + 4y - 20 = 0

4y = 20

y = 5

Therefore

value of x = 0

value of y = 5

Answer 2

Answer:

y=5, x= Aparibhasit

Step-by-step explanation:

5x-6y+30=0

5x+4y-20=0

Gatane par.....

-10y+50=0

-10y=-50

10y=50

y=50÷10

y=5

y=5 .;5x-6y+30=0

5x-6×5+30=0

5x-30+30=0

5x=0

x=0÷5

x= Aparibhasit
