Question 202661
Solving for x in equation (i), we get x  =  6 – 2y


Substitute this value for x in equation (ii). This gives us: 


6 – 2y – 4y = 8
- 6y  =  2
{{{y  =  -1/3}}}

Substitute this value for y in equation (ii):     {{{x - 4(-1/3) = 8}}}


{{{x + 4/3 = 8}}}, or {{{x = 8 - 4/3}}}, or {{{x = 20/3}}}
