5 plus 6b plus 12c plus 10b minus 4c minus 2 what is the coefficient of varieble b

The coefficient of variable b in the expression is obtained by combining like terms.

The expression is: 5 + 6b + 12c + 10b - 4c - 2

Combining like terms, we can simplify it as follows:

(6b + 10b) + (5 - 2) + (12c - 4c)

Adding the coefficients of b together: 6 + 10 = 16

Therefore, the coefficient of variable b is 16.
