3a=1divide both sides by 3a=1/3
-3a-12 = 12+12 +12-3a = +12~ ~-3 -3a = -8
3a = 21 Therefore, a = 21/3 a = 7
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
Oh, what a happy little question! When we see "3a squared," we simply need to multiply 3 by a and then square the result. So, 3a squared is the same as 3 times a times a, which simplifies to 3a^2. Just like painting a beautiful landscape, math can be a lovely adventure of discovery and creativity.
3a squared b squared

(3 x 3) - 6 = 3 3a-6=3 3a=3+6 3a=9 a=9/3 a=3
3a = 1a = 1/3 (a third)
5
3a=1divide both sides by 3a=1/3
(2a - 3)(3a - 4)
-3a-12 = 12+12 +12-3a = +12~ ~-3 -3a = -8
3a = 21 Therefore, a = 21/3 a = 7
2a2 x 3a-3 = (2 x 3)a(2 + -3) = 6a-1
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
