2x+4 = -16 2x = -16-4 2x = -20 x = -10
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
2x + 4 = 16 2x = 16 - 4 2x = 12 x = 12/2 x = 6
3x-4=5x+6 gives: 2x=-10 which gives x=-5
2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
2x + 10 = 182x = 8x = 4
If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.
