Question 386195: I am having toruble with substitution. I dont understand how to find the solution. A problem I am stuck on is y= 8x-5 y=2x+1 Answer by scott8148(6628) (Show Source):
You can put this solution on YOUR website! substitute the EQUIVALENT value for y from one equation into the other equation
this should leave an equation with only x in it
in the 1st equation , y equals (8x-5) ; (8x-5) is the equivalent value
substituting into the 2nd equation ___ (8x-5) = 2x+1
solving for x ___ 6x = 6 ___ x = 1
substituting back to find y ___ y = 8(1) - 5 ___ y = 3
