12a
10ab + 15b = 5b (2a + 3)
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
15b/39b4 = 5/13*b-3
12a^2
Re-ordering it : 13a - a -15b + 2b = 12a - 13b
12a
18c+18c+30=66f
13 + 18c = 607 18c = 607 - 13 18c = 594 c = 33
10ab + 15b = 5b (2a + 3)
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
12a-a = 11a
3 x 5 x b = 15b No exponents required.
18C warmer than -13C is 5C.
-24
Yes, it is a 12a
15b/39b4 = 5/13*b-3
