Question 42175
{{{3x +4y =12}}}
or {{{4y=12-3x}}}
or {{{y=(12-3x)/4}}}
or {{{y=3-3x/4}}} ________(1)


{{{3x +4y =12}}}
or {{{3x=12-4y}}}
or {{{x=(12-4y)/3}}}
or {{{x=4-4y/3}}} _________(2)



From (1)
When x = 0, {{{y = 3 -3*0/4=3}}}
When {{{x=8/3}}}, {{{y = 3 -3*(8/3)/4=1}}}


From (2)
When y=0, {{{x=4-4*0/3}}}
When {{{y=3/4}}}, {{{x=4-4*(3/4)/3=3}}}
 

Hence, the ordered pairs are: 
(0,3) ; (3,{{{3/4}}}) ; (4,0) ; ({{{8/3}}},1)
