Solving linear equations by addition
WebUse elimination to solve for x and y. And they gave us two equations here-- x plus 2y is equal to 6 and 4x minus 2y is equal to 14. So to solve by elimination, what we do is we're going to add these two equations together so that one of the two variables essentially gets eliminated, gets canceled out. WebThe subtraction property means that subtracting the same number from both sides of an equation will produce an equivalent equation. x + 3 = 5. x + 3 - 3 = 5 - 3 (Subtract 3 from both sides) x = 5 - 3 (3 on the left cancels out) x = 2. For each of the following questions, solve for X. You will need a calculator and scratch paper.

WebPlus 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.
