12 x = 144
x = 12
x = 12

-12x-25=-169 add 25 to both sides
-12x=-144 divide both sides by -12
x=12
-12x=-144 divide both sides by -12
x=12

- 12x - 25 = -169
- 12x = - 169 + 25
- 12x = - 144
x = -144/-12
= 12
- 12x = - 169 + 25
- 12x = - 144
x = -144/-12
= 12

-169 = -12x - 25
-144 = -12x
12 = x
-144 = -12x
12 = x
