0.10+(0.15)(20)=(0.12)(x+20)

Solution for 0.10+(0.15)(20)=(0.12)(x+20) equation:

Simplifying
0.10 + (0.15)(20) = (0.12)(x + 20)

Multiply 0.15 * 20
0.10 + 3 = (0.12)(x + 20)

Combine like terms: 0.10 + 3 = 3.1
3.1 = (0.12)(x + 20)

Reorder the terms:
3.1 = 0.12(20 + x)
3.1 = (20 * 0.12 + x * 0.12)
3.1 = (2.4 + 0.12x)

Solving
3.1 = 2.4 + 0.12x

Solving for variable 'x'.

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

Add '-0.12x' to each side of the equation.
3.1 + -0.12x = 2.4 + 0.12x + -0.12x

Combine like terms: 0.12x + -0.12x = 0.00
3.1 + -0.12x = 2.4 + 0.00
3.1 + -0.12x = 2.4

Add '-3.1' to each side of the equation.
3.1 + -3.1 + -0.12x = 2.4 + -3.1

Combine like terms: 3.1 + -3.1 = 0.0
0.0 + -0.12x = 2.4 + -3.1
-0.12x = 2.4 + -3.1

Combine like terms: 2.4 + -3.1 = -0.7
-0.12x = -0.7

Divide each side by '-0.12'.
x = 5.833333333

Simplifying
x = 5.833333333
