8a+4a=144 12a=144 12a/12=144/12 A=144
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+2b
2a + 11a - 5a = 8a

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
a=5: c=4
It is an equation in the single unknown variable, a. a = -4
8a = 12 so a = 1.5
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
8a+b+32a+3b=40a+4b
Add 8a to each side: -6a + 14 = 2 Subtract 14 from each side: -6a = -12 Divide each side by -6: a = 2. Job done.
