y+3x=5;x=-1,0,2

y + 3x  =  5

 

To find  y  when  x = -1  , replace  " x " in our equation with  " -1 "  and solve for  y .

 

y + 3(-1)  =  5           Multiply  3  and  -1  to get  -3 .

y - 3  =  5                 Add  3  to both sides of this equation.

y  =  5 + 3

y  =  8

 

So......         when   x  =  -1  ,   y  =  8  .

 

 

To find  y  when  x = 0  , replace  " x " in our equation with  " 0 "  and solve for  y .

 

y + 3(0)  =  5

y + 0  =  5

y  =  5

 

So......         when   x  =  0  ,   y  =  5  .

 

 

To find  y  when  x = 2  , replace  " x " in our equation with  " 2 "  and solve for  y .

Can you finish this one from here?     smiley
