11a-3a =8a so 8a+9=-7 8a = -16 a=-2
15-3 times 2 equals 15-6 equals 9.
If 8a = 40 then a must = 5So: 2*5-4 = 6
If the question is, What x 3 equals 15? Then 5 x 3 = 15 If the question is, What is 15 x 3? Then 15 x 3 = 45
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
8a = 12 so a = 1.5
a = 3 !
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
a^2 + 8a + 15
A = 4
A/-4.2 = 8A = -33.6
8a/-9=12 8a=12x-9 8a=-108 a=-108/8 a=-13.5 Hence the required answer is -13.5
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
This shouldn't be too hard for you if you know the basic concept and the way in which these questions are solved.(basically by ur Q im guessing you want 'a' on its own)8a - 15 = -3 (pretend that the '=' sign is a bridge and you want all the numbers without a letter next to them to be on on side and you want the number with letters next to them to be on the other side)(also when you bring '-15' onto the other side, it goes from a negative number to a positive number because it crossed the bridge)so it should look like this 8a = -3 + 15you should be ale to solve this. it should look like this: 8a = 12next divide 12 by 8 and you should get 12/8 = 3/2 so a = 3/2hope this helped :) x
15 of 0.2 equals 3.
15-3 times 2 equals 15-6 equals 9.
