Question

Solve for x.

x - 10 = -30



x = -40
x = -20
x = 20
x = 40

Answer 1

you want to get x by itself. To do this you would do the opposite operation. since its negative 10 you want to add 10 to both sides.

Answer 2

adding 10 to both sides gives you x = -20

Answer 3

To solve the equation you need to use the Addition Property of Equality. This property of equality gives you the ability to add the same number to both sides of an equation.

To solve, you would add -10+10, giving you 0, then you would 10 to -30, leaving you with the equation x=-20. Since you cannot simplify any further, your final answer is x=-20.
