Which of these isolate x or y?

dtan5457 · Answer

x + y = 6 
x = y + 5

Which of these plug the 2nd one (isolation of x) into the 1st equation?

?? Not good at this stuff explain plz @dtan5457

dtan5457 · Answer

When you solve a system by substitution....

You take y=whatever or x=whatever

to plug into the 2nd equation.

dtan5457 · Answer

x + y = 6
x = y + 5

you know that x=y+5 

plug that into x+y=6
