t+4 then divide by 9
Answers
Answer:
Here's an example of how division is the inverse operation of multiplication:
If we start with 7, multiply by 3, then divide by 3, we get back to 7:
7 \cdot 3 \div 3 = 77⋅3÷3=77, dot, 3, divided by, 3, equals, 7
Here's an example of how multiplication is the inverse operation of division:
If we start with 8, divide by 4, then multiply by 4, we get back to 8:
8 \div 4 \cdot 4 = 88÷4⋅4=88, divided by, 4, dot, 4, equals, 8
Solving a multiplication equation using inverse operations
Let's think about how we can solve for ttt in the following equation:
\qquad 6t = 546t=546, t, equals, 54
We want to get ttt by itself on the left hand side of the equation. So, what can we do to undo multiplying by 6?
We should divide by 6 because the inverse operation of multiplication is division!
Here's how dividing by 6 on each side looks:
\begin{aligned} 6t &= 54 \\\\ \dfrac{6t}{\blueD{6}} &= \dfrac{54}{\blueD{ 6}}~~~~~~~~~~\small\gray{\text{Divide each side by six.}} \\\\ t &= \greenD{9}~~~~~~~~~~\small\gray{\text{Simplify.}} \end{aligned}
