Add:(3g-4)-2(3g+4). The answer should be in mixed number form
To simplify the expression (3g-4)-2(3g+4), we need to distribute the -2 to both terms inside the parentheses.
So, (-2)*(3g) = -6g, and (-2)*(4) = -8.
Now we can substitute these values into the expression:
(3g-4)-2(3g+4) = 3g - 4 - 6g - 8
To combine like terms, we can add the coefficients of the "g" terms and the constant terms separately:
3g - 6g - 4 - 8 = (3g - 6g) + (-4 - 8) = -3g - 12
Therefore, the simplified expression is -3g - 12.
