There are three ways to solve systems of linear equations: by elimination (sometimes called addition), by substitution, and by creating a graphical representation. in your real-world scenario, discuss advantages and disadvantages of using each of the three ways. initial posts should include two or more variables (such as the number of boys and the number of girls) and have two or more equations involving those variables (such as there are twice as many girls as boys and that there are 33 children altogether). response posts in this option should show a solution using one of the three ways.

Aking and his army will attempt to capture a fortress. the left and right flanks break off from the main group to attack the west and east guard towers. suppose the left flank has a 60% chance of success and the right flank has a 75% chance of success, independently of one another. if both flanks capture their respective targets, then the king has a 98% chance of successfully taking the fort. if, however, only the left flank captures its tower, the king has an 80% chance of success; if only the right flank succeeds, the king has a 50% chance. if both flanks fail, then the king's chance of capturing the fort drops to 20%. it turns out the king captures the fort. what is the probability that one, and only one, flank was successful (either the left, or the right, but not both)? (round your answer to 3 decimal places)
