0.7(3x+6)=1.4-(x+2)

Solution for 0.7(3x+6)=1.4-(x+2) equation:

Simplifying
0.7(3x + 6) = 1.4 + -1(x + 2)

Reorder the terms:
0.7(6 + 3x) = 1.4 + -1(x + 2)
(6 * 0.7 + 3x * 0.7) = 1.4 + -1(x + 2)
(4.2 + 2.1x) = 1.4 + -1(x + 2)

Reorder the terms:
4.2 + 2.1x = 1.4 + -1(2 + x)
4.2 + 2.1x = 1.4 + (2 * -1 + x * -1)
4.2 + 2.1x = 1.4 + (-2 + -1x)

Combine like terms: 1.4 + -2 = -0.6

4.2 + 2.1x = -0.6 + -1x

Solving for variable 'x'.

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

Add 'x' to each side of the equation.
4.2 + 2.1x + x = -0.6 + -1x + x

Combine like terms: 2.1x + x = 3.1x
4.2 + 3.1x = -0.6 + -1x + x

Combine like terms: -1x + x = 0
4.2 + 3.1x = -0.6 + 0
4.2 + 3.1x = -0.6

Add '-4.2' to each side of the equation.
4.2 + -4.2 + 3.1x = -0.6 + -4.2

Combine like terms: 4.2 + -4.2 = 0.0
0.0 + 3.1x = -0.6 + -4.2
3.1x = -0.6 + -4.2

Combine like terms: -0.6 + -4.2 = -4.8
3.1x = -4.8

Divide each side by '3.1'.
x = -1.548387097
