5a - 10 = 4a + 8 is a linear equation in one variable.
28
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
14
Minus 8 plus 6 equals -2.
5a - 10 = 4a + 8 is a linear equation in one variable.
6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.
28
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
14
Minus 8 plus 6 equals -2.
Commutative property of addition.

(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4
-8a + 3a = (-8 + 3)a = (5)a = 5a
y=5a-3b+c a=12b=4c=8 a=8 b=2/3 c=2 y=5(8)-3(2/3)+(4) y=40-2+4 y=38 y = 823
9a +8 -2a -3 -5a = 2a +5
