3 + 6s = 4(s + -3) + 19
Reorder the terms:
3 + 6s = 4(-3 + s) + 19
3 + 6s = (-3 * 4 + s * 4) + 19
3 + 6s = (-12 + 4s) + 19
Reorder the terms:
3 + 6s = -12 + 19 + 4s
Combine like terms: -12 + 19 = 7
3 + 6s = 7 + 4s
Solving
3 + 6s = 7 + 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.
3 + 6s + -4s = 7 + 4s + -4s
Combine like terms: 6s + -4s = 2s
3 + 2s = 7 + 4s + -4s
Combine like terms: 4s + -4s = 0
3 + 2s = 7 + 0
3 + 2s = 7
Add '-3' to each side of the equation.
3 + -3 + 2s = 7 + -3
Combine like terms: 3 + -3 = 0
0 + 2s = 7 + -3
2s = 7 + -3
Combine like terms: 7 + -3 = 4
2s = 4
Divide each side by '2'.
s = 2
Simplifying
s = 2
