Simplifying
a = 3a + 12
Reorder the terms:
a = 12 + 3a
Solving
a = 12 + 3a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3a' to each side of the equation.
a + -3a = 12 + 3a + -3a
Combine like terms: a + -3a = -2a
-2a = 12 + 3a + -3a
Combine like terms: 3a + -3a = 0
-2a = 12 + 0
-2a = 12
Divide each side by '-2'.
a = -6
Simplifying
a = -6
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
12!

(x+3)(x+4) = x²+7x+12
If you ignore the fact that the question contains the phrase "3 time's 3" which is without any meaning, the answer is 89333197.32.
(x + 3)(x + 4) = x2 + 7x + 12
x^2 +7x+12 = (x+3)(x+4) when factored
x=-24
If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
(x+3)(x+4)=x2+7x+12
