WebDec 11, 2024 · Step by step guide to solve systems of equations . A system of equations contains two equations with similar two variables. For example, consider the system of equations: \(x -y=1, x+y=5\) The easiest way to solve a system of equations is using the elimination method. The elimination method uses the addition property of equality. WebWhen solving inequalities, like, say, this one: -2x+5<25. You would cancel out the +5 with -5 and subtract 25 by 5, so you're left with this: -2x<20. But now, since you're dividing by -2 (remember that multiplying or dividing by a negative number will reverse the sign) it will no longer be less than, it will be greater than: -2x/-2>20/-2.
