Question

slove the following simultaneous
x + 5y = 15; 2x – 3y = 1
​

Answer 1

Answer:

x=1, y= -2

Step-by-step explanation:

4x-3y=10

4x=10+3y

x=10+3y / 4 ---- (I)

3x+y=1

3(10+3y / 4) +y=1

30+9y / 4 +y =1

30+9y +4y / 4 =1

30+13y = 4

13y = 4 - 30

y = -26/13

y= -2

putting the value of x in eqn (I)

x=10+3y / 4

x=10+3(-2) /4

x=10-6 /4

x= 4/4

x=1
