0.15x+0.05(12-x)=0.10(-10)

Solution for 0.15x+0.05(12-x)=0.10(-10) equation:

Simplifying
0.15x + 0.05(12 + -1x) = 0.10(-10)
0.15x + (12 * 0.05 + -1x * 0.05) = 0.10(-10)
0.15x + (0.6 + -0.05x) = 0.10(-10)

Reorder the terms:
0.6 + 0.15x + -0.05x = 0.10(-10)

Combine like terms: 0.15x + -0.05x = 0.1x
0.6 + 0.1x = 0.10(-10)

Multiply 0.10 * -10
0.6 + 0.1x = -1

Solving
0.6 + 0.1x = -1

Solving for variable 'x'.

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

Add '-0.6' to each side of the equation.
0.6 + -0.6 + 0.1x = -1 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + 0.1x = -1 + -0.6
0.1x = -1 + -0.6

Combine like terms: -1 + -0.6 = -1.6
0.1x = -1.6

Divide each side by '0.1'.
x = -16

Simplifying
x = -16
