0.35x+0.25(4-x)=0.3(-1)

Solution for 0.35x+0.25(4-x)=0.3(-1) equation:

Simplifying
0.35x + 0.25(4 + -1x) = 0.3(-1)
0.35x + (4 * 0.25 + -1x * 0.25) = 0.3(-1)
0.35x + (1 + -0.25x) = 0.3(-1)

Reorder the terms:
1 + 0.35x + -0.25x = 0.3(-1)

Combine like terms: 0.35x + -0.25x = 0.1x

Multiply 0.3 * -1
1 + 0.1x = -0.3

Solving
1 + 0.1x = -0.3

Solving for variable 'x'.

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

Add '-1' to each side of the equation.
1 + -1 + 0.1x = -0.3 + -1

Combine like terms: 1 + -1 = 0
0 + 0.1x = -0.3 + -1
0.1x = -0.3 + -1

Combine like terms: -0.3 + -1 = -1.3
0.1x = -1.3

Divide each side by '0.1'.
x = -13

Simplifying
x = -13
