Whan a = 2 and b = 6,
5a + 2b = 5*2 + 2*6 = 10 + 12 = 22
Five thirds (five over three)
2a+5a+9a = 16a
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
5a plus 2b
a = 0
8a+2b
no
Gathering like terms together, this is equal to 5a + 3b + 7c.
-2a plus 3b
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
5a(a+2b+b²)
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus
Five thirds (five over three)
2a+5a+9a = 16a
Yes.
