Just as you would solve an equation, to solve an inequality, you must use inverse operations to isolate the variable, which, in this example, is x. You can isolate x easily by adding 3 to both sides of the inequality sign as follows: x - 3 > 7. x -3 + 3 > 7 +3. x > 10. Now the inequality is solved! The answer is x>10. Instead, problems with equations that have multiple variables will usually ask you to solve for one of the variables. You'll simplify it as much as you can, with the variable you're solving for on one side of the equation and any other numbers and variables on the other. Let's simplify the expression above: 2x +6y - 10 = 38.

General strategy for solving linear equations. Step 1. Simplify each side of the equation as much as possible. Use the Distributive Property to remove any parentheses. Combine like terms. Step 2. Collect all the variable terms on one side of the equation. Use the Addition or Subtraction Property of Equality. Step 3.

You get x is equal to 15. To solve this one, add 5 to both sides of this equation. x is equal to negative 5. So our solution, there's two x's that satisfy this equation. x could be 15. 15 minus 5 is 10, take the absolute value, you're going to get 10, or x could be negative 5. Negative 5 minus 5 is negative 10.
