Real-life examples of linear equations include distance and rate problems, pricing problems, calculating dimensions and mixing different percentages of solutions. One application of linear equations is illustrated in finding the time it takes for two cars moving toward each other at different speeds to reach the same point. Another example is estimating how much a shirt on sale for $20 and marked down by 35 percent cost before the sale.
