which one do you think? you substitute the the first equation into the second equation
Mehek14
  • Mehek14
in the first equation, y = x + 1 substitute that value for y in the second equation tell me what you get @automaticloveletter

5 = y-4x? (I'm using a calculator) :/

no need for a calculator

look the value of y in the first equation is x + 1 correct?
automaticloveletter
  • automaticloveletter
yes
Mehek14
  • Mehek14
so when you substitute it into the second equation, you put x + 1 instead of y
automaticloveletter
  • automaticloveletter
wait so it's just 4*1+5?
Mehek14
  • Mehek14
no you're not getting it.... y = x + 1 in the first equation second equation y = 4x + 5 put x + 1 instead of y in the second equation you get: x + 1 = 4x + 5

  • automaticloveletter
ohhh
Mehek14
  • Mehek14
you just substitute the value in the first equation into the second they're not asking you to solve it

I know that, but I'd also want to know how to solve it for other questions..

  • Mehek14
How you would solve for it: \(x + 1 = 4x + 5\\1 = 3x + 5\\-4=3x\\ -\dfrac{4}{3}=x\)
