Answer 1

5x+8= -2
5x -2 -8
5x = -10
x = -10/5
x = -2



4-2x =8
4-8 = 2x
-4 = 2x
-4/2 = x
-2 = x



10 = 2x+6
10-6 = 2x
4= 2x
4/2 = x
2= x



-16=2-9x
-16-2 = 9x
-18= 9x
-18/9 = x
-2 = x


3-2x=2-3x
3x -2x = 2-3
x = -1

-6x=24
24 = 6x
24/6 = x
4 = x


5x/2 -7=1/2 mcm = 2
5x -14 = 1
5x = 1+14
5x ='15
x = 15/5
x = 3
