6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
8a+4a=144 12a=144 12a/12=144/12 A=144
8a+2b
2a + 11a - 5a = 8a
You combine like terms so... 13a+12=54. Subtract 2 from both sides and you get 13a=52 . Then divide both sides by 13 and you get 4.. (:

6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
A = 4
It is an equation in the single unknown variable, a. a = -4
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.
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
8a+4a=144 12a=144 12a/12=144/12 A=144
a=5: c=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
a^2 + 8a + 15
