Simplifying
3a + -7 = 12 + 4a
Reorder the terms:
-7 + 3a = 12 + 4a
Solving
-7 + 3a = 12 + 4a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4a' to each side of the equation.
-7 + 3a + -4a = 12 + 4a + -4a
Combine like terms: 3a + -4a = -1a
-7 + -1a = 12 + 4a + -4a
Combine like terms: 4a + -4a = 0
-7 + -1a = 12 + 0
-7 + -1a = 12
Add '7' to each side of the equation.
-7 + 7 + -1a = 12 + 7
Combine like terms: -7 + 7 = 0
0 + -1a = 12 + 7
-1a = 12 + 7
Combine like terms: 12 + 7 = 19
-1a = 19
Divide each side by '-1'.
a = -19
Simplifying
a = -19
