Question

solve the simultaneous equations; 3x+ 6y=6 ; x-5y = 2​

Answer 1

Step-by-step explanation:

3x+6y=6(let eq.1)

x-5y=2(eq.2)

by multiplying eq.1 by 5

in eq.2 multiplying by 6

now,add both equation

then, eq. becomes

15x+30y= 30

6x-30y=12

then added both equation

21x =42

so,x= 2

putting the value of x in eq. 2

2-5y=2

-5y= 2-2

-5y=0

so,y=0

hence, x=2 and y=0
