x-2+4=-8 x+2=-8 x=-10
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
-4
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
5(-2)+(-3)(-4) =-(10)+12 =2
4
x = -2
-2
2 x 2 = 4 x 60 = 240
x = -2
4
4
-(2)Squared = 4
-x -2 = 2 so -x = 2+2 = 4 and so x = -4
4 + x = 2x --> 4 = 2x - x --> 4 = x: x = 4
No, it is not.
