Linear Equation Word Problem. Problem stated in words are known as word problems. Solving word problem consists two steps. First step is translating the words of the problem into an algebraic equation. Second step is solving the equation. Let's see some examples. Example 1. If 7 is added to three times of a number, then the result is 28. Find ...
A linear equation is an algebraic equation where the highest power on the variable is one. When graphed, a linear equation will produce a straight line. There are a few ways that we can write linear equations, with two of the most common being slope-intercept form and standard form.
