What happens if you have an equation too big to graph? Learning Target: Solving Systems of Equations Shack’s 1st Period What happens if you have an equation too big to graph? y= 12x + 4 y = -2x + 13 What does the word Substitution mean? If x =  Then where would the  go in this equation? 2x+5 = 10………..???
