0.45x+0.05(12-x)=0.10(22)

Solution for 0.45x+0.05(12-x)=0.10(22) equation:

Simplifying
0.45x + 0.05(12 + -1x) = 0.10(22)
0.45x + (12 * 0.05 + -1x * 0.05) = 0.10(22)
0.45x + (0.6 + -0.05x) = 0.10(22)

Reorder the terms:
0.6 + 0.45x + -0.05x = 0.10(22)

Combine like terms: 0.45x + -0.05x = 0.4x
0.6 + 0.4x = 0.10(22)

Multiply 0.10 * 22
0.6 + 0.4x = 2.2

Solving
0.6 + 0.4x = 2.2

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 + 0.4x = 2.2 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + 0.4x = 2.2 + -0.6
0.4x = 2.2 + -0.6

Combine like terms: 2.2 + -0.6 = 1.6
0.4x = 1.6

Divide each side by '0.4'.
x = 4

Simplifying
x = 4
