Forming linear equations to solve problems
WebHere are a few ways to identify a linear equation: Look at the degree of the equation, a linear equation is a first-degree equation. Check if the equation has two variables. … WebEvery linear equation can be solved in the same way as in the above examples. In fact, let us consider the general linear equation ax+b=0 Add − b to both sides to obtain ax=− b Multiply both sides by 1a to obtain x=− (ba) if a a≠0. The general linear equation, therefore, has as its solution set {ba}, if a≠0.
