It simplifies to 5a+4 !
2a+5a+9a = 16a
Whan a = 2 and b = 6, 5a + 2b = 5*2 + 2*6 = 10 + 12 = 22

It simplifies to 5a+4 !
3a4 - 2a2 + 5a - 10 - 2a4 + 4a2 + 5a - 2 = a4 + 2a2 + 10a - 12 = a4 + (2a - 2)(a + 6)
2a+5a+9a = 16a
5a+5=6a-7
a + 3a + 5a = 180 9a =180 a = 20
Answer to: 5a + 1 = a - 3a = -1
Whan a = 2 and b = 6, 5a + 2b = 5*2 + 2*6 = 10 + 12 = 22
a = 0
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
