Please solve: 2x + 4 (less than or equal to) -8?

x<= -6

2x + 4 ≤ -8
2x ≤ -8 - 4
x ≤ -12/2
x ≤ -6

2x + 4 ≤ - 8

2x ≤ - 12

x ≤ - 6

2x+4 < -8
-4 -4
---------------------
2x<-12
--- ---
2 2

x is less than or equal to -6

subtract 4 on both sides
2x +4 -4 (less than/equal to) -8 -4

4's on left side canel out..rite side add up
2x (less than/equal to) -12

divide 2 on both sides to cancel out 2 to get x by itself
2x/2 (less than equal to) -6

x is now by itself so yu have the final answer...
x (less than/equal to) -6

x </= -6
