A student solved the equation 6s - 10 = 2 + 3s + s and got s = -4. His work shown below is his check for this problem
Which statement best applies to the work shown?
6(-4)- 10 = 2+36-4)+(-4)
-24 - 10 = 2 + (-12)+(-4)
-34 = -14
A. His check does not work, thus s = -4.
B. The work in his check is all correct, thus s = -34.
C. The work in his check is all correct, thus s = -4.
D. His check does not work, thus s#-4.
