Solve for x: 7x-3=-5x-18 please show work.?

7x - 3 = -5x - 18
7x + 5x = 3 - 18
12x = -15
x = -15/12
x = -5/4 (-1.25)

12 x = - 15
x = - 15 / 12
x = - 5 / 4

7x -3 = -5x -18 [ add 18 on both sides ]
7x +15 = -5x [ subtract 7x on both sides ]
15 = -12x [ divide ]
x = 15/-12 [ simplify ]
x = 5/-4 [ that's your anwer ]

7x-3=-5x-18
+5x +5x
12x-3=-18
+3 +3
12x=-15
x=1.25
