Answer
a=-7
Work Step by Step
Simplifying
2a + 4 = a + -3
Reorder the terms:
4 + 2a = a + -3
Reorder the terms:
4 + 2a = -3 + a
Solving
4 + 2a = -3 + 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.
4 + 2a + -1a = -3 + a + -1a
Combine like terms: 2a + -1a = 1a
4 + 1a = -3 + a + -1a
Combine like terms: a + -1a = 0
4 + 1a = -3 + 0
4 + 1a = -3
Add '-4' to each side of the equation.
4 + -4 + 1a = -3 + -4
Combine like terms: 4 + -4 = 0
0 + 1a = -3 + -4
1a = -3 + -4
Combine like terms: -3 + -4 = -7
1a = -7
Divide each side by '1'.
a = -7
Simplifying
a = -7
