Question

(3g-4) -2(3g+4)

Answer 1

To simplify the expression $(3g-4)-2(3g+4)$, follow these steps:

1. Distribute the $-2$ across the terms in the parentheses: $$-2(3g+4)=-2\cdot 3g-2\cdot 4=-6g-8$$

2. Substitute this back into the expression: $$(3g-4)-(6g+8)$$

3. Rewrite the expression: $$3g-4-6g-8$$

4. Combine like terms:

   • Combine the $g$ terms: $3g-6g=-3g$
   • Combine the constants: $-4-8=-12$

5. The final result is: $$-3g-12$$

Thus, the simplified expression is: $$-3g-12$$
