We know the binary linear equations ax + by = - 16 CX + 20Y = - 224 about X and Y. the solution of the binary linear equations is x = 8, y = - 10. A student copied C wrong in his solution, and all other solutions are correct. He solved x = 12, y = - 13, and solved a + B + C

According to the meaning of the title
8a-10b=-16
12a-13b=-16
∴a=3
b=4
8c-80=-224
∴c=-16
∴a+b+c=3+4-16=-9
