3a - 1 = ? relation between a & 3 is ( 3 multiplied by a ) since a = 8, then, 3 * 8 = 24 therefore : (3*8)-1=23
3*5 - 8 = 15-8 = 7
Subtract 8 from each side: 3a = 33 Divide each side by 3: a = 11
(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
-3a-12 = 12+12 +12-3a = +12~ ~-3 -3a = -8
-8a + 3a = (-8 + 3)a = (5)a = 5a
9 - 3a = 8Add 3a to each side:9 = 8 + 3aSubtract 8 from each side:1 = 3aDivide each side by 3:1/3 = a
3a - 1 = ? relation between a & 3 is ( 3 multiplied by a ) since a = 8, then, 3 * 8 = 24 therefore : (3*8)-1=23
3*5 - 8 = 15-8 = 7
Subtract 8 from each side: 3a = 33 Divide each side by 3: a = 11
6a + 8 = 2(3a + 4)
12+1.5a = 3a 12 = 3a-1.5a 12 = 1.5a Divide both sides by 1.5 to find the value of a: a = 8
5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
(5a+8) - (2a+4) =3a +4 To do this, simply subtract like terms. 5a-2a=3a and 8-4=4
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
(3a-8) + 5x(a)
