2.1 = (w + 3)(42)

Reorder the terms:
2.1 = (3 + w)(42)

Reorder the terms for easier multiplication:
2.1 = 42(3 + w)
2.1 = (3 * 42 + w * 42)
2.1 = (126 + 42w)

Solving
2.1 = 126 + 42w

Solving for variable 'w'.

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

Add '-42w' to each side of the equation.
2.1 + -42w = 126 + 42w + -42w

Combine like terms: 42w + -42w = 0
2.1 + -42w = 126 + 0
2.1 + -42w = 126

Add '-2.1' to each side of the equation.
2.1 + -2.1 + -42w = 126 + -2.1

Combine like terms: 2.1 + -2.1 = 0.0
0.0 + -42w = 126 + -2.1
-42w = 126 + -2.1

Combine like terms: 126 + -2.1 = 123.9
-42w = 123.9

Divide each side by '-42'.
w = -2.95

Simplifying
w = -2.95
