<h2>Answer:</h2>

Our functions are:

f(x) = -5x + 12\\g(x) = -\frac{3}{2}x + 4\\

To solve this, we must use the expression g(-10) - f(3).

-\frac{3}{2}(-10) + 12 - [-5(3)] + 12\\\\15 + 12 - [-5(3)] + 12\\\\15 + 12 - (-15) + 12\\\\27 - (-15) + 12\\\\42 + 12\\\\54

The value of the expression g(-10) - f(3) is <em>15</em>.
