It looks like you have three equations, C1, C2, and C3, involving two variables, x1 and x2.
C1 = 5x2 - 3x1 - 5C2 = 7 - 3x1 + 2x2C3 = 5x1 - 5x2 - 5
If you want to find the values of x1 and x2 that satisfy all three equations simultaneously, you can solve the system of equations by substitution or elimination methods.
