f(x)= 4x-15 g(x)= 6x+31
what value does x have to be when f(x)= g(x)?
Not really sure how to approach this problem so any help would really be appreciated :)
+36916 4x-15 = 6x+31 when they are equal, it is a point of intersection of these two lines ....subtract 4x from both sides to get
-15 = 2x + 31 now subtract 31 from both sides to get
-46 = 2x now divide both sides by two
x = - 23 this ould be the x value where f(x) = g(x)
