14a - 4a + 5a - 3a = 12a
so 5a = -20 making a = -4
5a or 4a squared
5a - 10 = 4a + 8 is a linear equation in one variable.
5a
5a+3a2a2= 8a a2
11a+11b
3a2 - 16a + 5 = 3a2 - 15a - a + 5 = 3a(a -5) - 1(a -5) = (3a - 1)(a - 5)
12a
4a + 7
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
