21 x 13 = 273
4x+13 = 21 4x = 21-13 4x = 8 x = 2
273. Another way of stating this is if x/21=13, what is x? You can find x by multiplying both sides on the equation by 21. You'll end up with x=273.
3(x + 7) > 5x - 13 3x + 21 > 5x - 13 21 + 13 > 5x - 3x 34 > 2x 17 > x The solution set: {x| x < 17}
(13 - 6) x 5 = 56 - 21
21 x 13 = 273
4x+13 = 21 4x = 21-13 4x = 8 x = 2

3 x 7 x 7 x 11 x 13
13 x 21 is 273
The GCF of 42 and 273 is 21. 42 = 2 x 21 273 = 13 x 21
