2(s+1.6)-5(z-s)=1.9

Solution for 2(s+1.6)-5(z-s)=1.9 equation:

Simplifying
2(s + 1.6) + -5(z + -1s) = 1.9

Reorder the terms:
2(1.6 + s) + -5(z + -1s) = 1.9
(1.6 * 2 + s * 2) + -5(z + -1s) = 1.9
(3.2 + 2s) + -5(z + -1s) = 1.9

Reorder the terms:
3.2 + 2s + -5(-1s + z) = 1.9
3.2 + 2s + (-1s * -5 + z * -5) = 1.9
3.2 + 2s + (5s + -5z) = 1.9

Combine like terms: 2s + 5s = 7s
3.2 + 7s + -5z = 1.9

Solving
3.2 + 7s + -5z = 1.9

Solving for variable 's'.

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

Add '-3.2' to each side of the equation.
3.2 + 7s + -3.2 + -5z = 1.9 + -3.2

Reorder the terms:
3.2 + -3.2 + 7s + -5z = 1.9 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0
0.0 + 7s + -5z = 1.9 + -3.2
7s + -5z = 1.9 + -3.2

Combine like terms: 1.9 + -3.2 = -1.3
7s + -5z = -1.3

Add '5z' to each side of the equation.
7s + -5z + 5z = -1.3 + 5z

Combine like terms: -5z + 5z = 0
7s + 0 = -1.3 + 5z
7s = -1.3 + 5z

Divide each side by '7'.
s = -0.1857142857 + 0.7142857143z

Simplifying
s = -0.1857142857 + 0.7142857143z
