-9
3-6x=15 or,6x=3+15 or,6x=18 or,x=18/6 or,x=3 [Ans].
4x-1 = 6x-15 4x-6x = 1-15 -2x = -14 x = 7
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
you multiply it
8x+39 = 2x-15 6x = -54 x = -9
3-6x = 15 -6x = 15-3 -6x = 12 x = -2
6x-5 = 7, 6x = 7+5, 6x = 12, x = 2
I'm an orange!
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
40=4-6x 40-(4)=4-6x-(4) 36=-6x -6=x
-3 + 3x + 6x = 15 combine like terms 6x and 3x are like terms as are -3 and 15 9x = 18 x = 2
6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10
