4a - 9 = 27 4a = 36 a = 9
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
4a-2=7a-6 4=3a a=4/3
11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
4a - 9 = 27 4a = 36 a = 9
Solve the following equation for A : 2A/3 = 8 + 4A
Solve the following equation for A : 2A/3 = 8 + 4A
9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1
4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5
9a + 4a = 26 13a = 26 a = 26/13 a = 2
4a-2=7a-6 4=3a a=4/3
11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3
4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
The given equation is 4a^2 - 16a = 0. Factoring out a common factor of 4a, we get 4a(a - 4) = 0. This equation is satisfied when either 4a = 0 or (a - 4) = 0. Solving these, we find that the solution set is a = 0 and a = 4.
8a+4a=144 12a=144 12a/12=144/12 A=144
You could divide 311 by 100 and multiply by 60 or divide 311 by 10 and multiply by 6 or multiply 311 by 0.6 and all will give 186.6 as the same result.
