s-w-a-r=4

Solution for s-w-a-r=4 equation:

Simplifying
s + -1w + -1a + -1r = 4

Reorder the terms:
-1a + -1r + s + -1w = 4

Solving
-1a + -1r + s + -1w = 4

Solving for variable 'a'.

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

Add 'r' to each side of the equation.
-1a + -1r + s + r + -1w = 4 + r

Reorder the terms:
-1a + -1r + r + s + -1w = 4 + r

Combine like terms: -1r + r = 0
-1a + 0 + s + -1w = 4 + r
-1a + s + -1w = 4 + r

Add '-1s' to each side of the equation.
-1a + s + -1s + -1w = 4 + r + -1s

Combine like terms: s + -1s = 0
-1a + 0 + -1w = 4 + r + -1s
-1a + -1w = 4 + r + -1s

Add 'w' to each side of the equation.
-1a + -1w + w = 4 + r + -1s + w

Combine like terms: -1w + w = 0
-1a + 0 = 4 + r + -1s + w
-1a = 4 + r + -1s + w

Divide each side by '-1'.
a = -4 + -1r + s + -1w

Simplifying
a = -4 + -1r + s + -1w
