Question

3-4a = a-16

Answer 1

Simplifying
3 + -4a = a + -16

Reorder the terms:
3 + -4a = -16 + a

Solving
3 + -4a = -16 + a

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-1a' to each side of the equation.
3 + -4a + -1a = -16 + a + -1a

Combine like terms: -4a + -1a = -5a
3 + -5a = -16 + a + -1a

Combine like terms: a + -1a = 0
3 + -5a = -16 + 0
3 + -5a = -16

Add '-3' to each side of the equation.
3 + -3 + -5a = -16 + -3

Combine like terms: 3 + -3 = 0
0 + -5a = -16 + -3
-5a = -16 + -3

Combine like terms: -16 + -3 = -19
-5a = -19

Divide each side by '-5'.
a = 3.8

Simplifying
a = 3.8
