Question

Q4 solve the equation by Elimination Method
y-2x=7
4y+x=1​

Answer 1

Answer:

Step-by-step explanation:

i) y-2x = 7. And. ii) 4y+x = 1

i) y=7+2x

Now replacing y by its value in (ii)

4(7+2x)+x = 1

28+8x+x = 1

28+9x = 1

9x = 1-28

9x = -27

x =  

Now y will be ;

4y + (-3) = 1

4y-3=1

4y=4
