Solution for 3+0.1(38-x)=1.8x-(0.4x-3.8) equation:


Simplifying
3 + 0.1(38 + -1x) = 1.8x + -1(0.4x + -3.8)
3 + (38 * 0.1 + -1x * 0.1) = 1.8x + -1(0.4x + -3.8)
3 + (3.8 + -0.1x) = 1.8x + -1(0.4x + -3.8)

Combine like terms: 3 + 3.8 = 6.8
6.8 + -0.1x = 1.8x + -1(0.4x + -3.8)

Reorder the terms:
6.8 + -0.1x = 1.8x + -1(-3.8 + 0.4x)
6.8 + -0.1x = 1.8x + (-3.8 * -1 + 0.4x * -1)
6.8 + -0.1x = 1.8x + (3.8 + -0.4x)

Reorder the terms:
6.8 + -0.1x = 3.8 + 1.8x + -0.4x

Combine like terms: 1.8x + -0.4x = 1.4x
6.8 + -0.1x = 3.8 + 1.4x

Solving
6.8 + -0.1x = 3.8 + 1.4x

Solving for variable 'x'.

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

Add '-1.4x' to each side of the equation.
6.8 + -0.1x + -1.4x = 3.8 + 1.4x + -1.4x

Combine like terms: -0.1x + -1.4x = -1.5x
6.8 + -1.5x = 3.8 + 1.4x + -1.4x
