2x-2< -12 or 2x+3> 7 = a. x < -7 or x > 5 b. x < -5 or x > 5 c. x < -5 or x > 2 d. x < -12 or x > 2

2x - 2 < -12 
2x < -12 + 2 add 2 to each side 
2x < -10 perform the addition on the right side 
x < -10 / 2 divide each side by 2 
x < -5 perform the division on the right side 

2x + 3 > 7 
2x > 7 - 3 subtract 3 from each side 
2x > 4 perform the subtraction on the right side
x > 4 / 2 divide each side by 2 
x > 2 perform the division on the right side 

These are just like equations, except the you have to change the direction of the sign when you multiply or divide by a negative number

(C) x < -5 or x > 2

You're doing something i dont know how to do but search up on google slope calculator maybe that will get you there
