6.3+1.2s=4(7.1-s)

Solution for 6.3+1.2s=4(7.1-s) equation:

Simplifying
6.3 + 1.2s = 4(7.1 + -1s)
6.3 + 1.2s = (7.1 * 4 + -1s * 4)
6.3 + 1.2s = (28.4 + -4s)

Solving
6.3 + 1.2s = 28.4 + -4s

Solving for variable 's'.

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

Add '4s' to each side of the equation.
6.3 + 1.2s + 4s = 28.4 + -4s + 4s

Combine like terms: 1.2s + 4s = 5.2s
6.3 + 5.2s = 28.4 + -4s + 4s

Combine like terms: -4s + 4s = 0
6.3 + 5.2s = 28.4 + 0
6.3 + 5.2s = 28.4

Add '-6.3' to each side of the equation.
6.3 + -6.3 + 5.2s = 28.4 + -6.3

Combine like terms: 6.3 + -6.3 = 0.0
0.0 + 5.2s = 28.4 + -6.3
5.2s = 28.4 + -6.3

Combine like terms: 28.4 + -6.3 = 22.1
5.2s = 22.1

Divide each side by '5.2'.
s = 4.25

Simplifying
s = 4.25
