Do the numbers first. The LCM of 6 and 8 is 24. Choose the higher of the variables. The LCM of 6a3 and 8a is 24a3
A = 4
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
So we have 5a + 11 + 3a - 7 = -4 Start by combining common terms such as the 5a and 3a to give you 8a and 11 and -7 to give you 4. So now your equation is 8a + 4 = -4. Subtract 4 from both sides gives you 8a = -8. Divide -8 by 8 to give you a = -1, your solution.
8a+4a=144 12a=144 12a/12=144/12 A=144
It is an equation in the single unknown variable, a. a = -4
8a = 12 so a = 1.5
a^2 + 8a + 15
a = 3 !
8a times (2 + 1)
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
8a - 15 = -3 8a = 15 - 3 8a = 12 a = 12/8 = 6/4 = 3/2
8a + 1 is in its simplest form and does not factor.
5x - 8a + 4a - 2x + a = 3x - 3a
Add 8a to each side: -6a + 14 = 2 Subtract 14 from each side: -6a = -12 Divide each side by -6: a = 2. Job done.
8a/-9=12 8a=12x-9 8a=-108 a=-108/8 a=-13.5 Hence the required answer is -13.5
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3
7x - 8a = 3x + 24a First, add 8a to both sides: 7x = 3x + 24a + 8a Now subtract 3x from both sides to get all x terms on one side: 7x - 3x = 24a + 8a Simplify... 4x = 32a And divide both sides by 4: x = 32a / 4 = 8a x = 8a
-8a + 3a = (-8 + 3)a = (5)a = 5a
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
