A+B = 12, A+B+C = 8 then find C?
A+B = 12, A+B+C = 8 then find C?
Explanation
We know A + B = 12.
We also know A + B + C = 8.
Substitute the value of A + B into the second equation: 12 + C = 8.
Solve for C: C = 8 - 12 = -4.
We know A + B = 12.
We also know A + B + C = 8.
Substitute the value of A + B into the second equation: 12 + C = 8.
Solve for C: C = 8 - 12 = -4.
