Question

will medal and fan!!
Which ordered pairs, in the form (x,y), are solutions to the equations?
3x-y/4=11
(3,8), (4, 4)

Answer 1

3x-(y/4)=11
subsitute
in (x,y) form
if (3,-8)
subsitute 3 for x and -8 for y
3(3)-(-8/4)=11
9-(-2)=11
9+2=11
11=11
(3,-8) is a valid soultion

try 4,4
subsittue 4 for x and 4 for y
3(4)-(4/4)=11
12-(1)=11
12-1=11
11=11
(4,4) is a valid solution

both are true so the answer,so.... both are solutions :) ~~~~Apologiabiology
