Question 915964


{{{ 3x - y/4 = 11}}} 

(3, -8); 

{{{ 3*3 - ((-8)/4 )= 11}}} 


{{{ 9 - (-2) = 11}}}

{{{ 9 +2 = 11}}}

{{{ 11 = 11}}}



(4,4) 

{{{ 3*4 - ((4)/4 )= 11}}} 


{{{ 12 - (1) = 11}}}

{{{ 12-1 = 11}}}

{{{ 11 = 11}}}

A. Yes, both are solutions 

see it on a graph:


 {{{drawing( 600, 600, -10, 10, -50, 10,locate(3,-8,p(3,-8)),locate(4,4,p(4,4)),circle(4,4,.2), circle(3,-8,.2), graph( 600, 600, -10, 10, -50, 10, 12x-44)) }}}
