If the solution of the equation 5x-2a = 6 + 4a-x about X is nonnegative, then the value range of a is A.a≥1 B.a≤-1 C,a≥-1 D.a≥0u

If the solution of the equation 5x-2a = 6 + 4a-x about X is nonnegative, then the value range of a is A.a≥1 B.a≤-1 C,a≥-1 D.a≥0u

5x-2a=6+4a-x
6x=6+6a
x=1+a
X is not negative
C,a≥-1
