Question

4(9x - 12) = 3(16x - 12)

Answer 1

x=-1

Answer 2

4(9x - 12) = 3(16x - 12)
36x - 48 = 48x - 36
-12 = 12x
x = -1

Answer 3

this is interesting
graph y=36x-48, and y=48x-36, the intersection is the solution

will y=ax-b and y=bx-a always have x=-1?

Answer 4

36x - 48 = 48x- 36
+48 +48
36x = 48x+12
-48x -48x
-12x = 12

divide by -12

-1x = 1

x = -1
