Some word problems in this chapter involve one "easy equation", usually found by translating a simple relationship between x and y (like one is twice the other or that they add to a given number). The second linear equation often uses a "rate times quantity" formula. This is true for • distance problems (rate time = distance) • mixture problems (percent concentration amount of solution = amount of concentrate) • money problems (value of one item = how many items...
2 examples please Some word problems in this chapter involve one "easy equation", usually found by translating a simple relationship between x and y (like one is twice the other or that they add to a given number).
