3(.70)=(w+3)(.42)

Solution for 3(.70)=(w+3)(.42) equation:

Simplifying
3(0.70) = (w + 3)(0.42)

Multiply 3 * 0.70
2.1 = (w + 3)(0.42)

Reorder the terms:
2.1 = (3 + w)(0.42)

Reorder the terms for easier multiplication:
2.1 = 0.42(3 + w)
2.1 = (3 * 0.42 + w * 0.42)
2.1 = (1.26 + 0.42w)

Solving
2.1 = 1.26 + 0.42w

Solving for variable 'w'.

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

Add '-0.42w' to each side of the equation.
2.1 + -0.42w = 1.26 + 0.42w + -0.42w

Combine like terms: 0.42w + -0.42w = 0.00
2.1 + -0.42w = 1.26 + 0.00
2.1 + -0.42w = 1.26

Add '-2.1' to each side of the equation.
2.1 + -2.1 + -0.42w = 1.26 + -2.1

Combine like terms: 2.1 + -2.1 = 0.0
0.0 + -0.42w = 1.26 + -2.1
-0.42w = 1.26 + -2.1

Combine like terms: 1.26 + -2.1 = -0.84
-0.42w = -0.84

Divide each side by '-0.42'.
w = 2

Simplifying
w = 2
