For each of the following questions, solve for X. You will need a calculator and scratch paper. the price is right tickets indianaWebPlus 2. The left-hand side just becomes an x. You have a less than or equal sign. That won't change by adding or subtracting the same thing to both sides of the inequality. And then 1 plus 2 is 3. So x needs to be less than or equal to 3. Any x that is less than or equal to 3 will satisfy this equation. the price is right tickets atlanta ga

"WebJun 14, 2024 · A. To solve a two-step equation with addition, start by combining any “like-terms”. For example, the equation 4 + x − 5 = − 9 + 1 would be simplified to x − 1 = − 8 by combining like-terms. Now the goal is to isolate the variable in order to solve for x. In order to get x alone, 1 needs to be added to both sides of the equation. " - Solving linear equations by addition
