monica has some cookies. she gave seven to her sister. then, she divided the remainder into two halfway, and she still had five

Answer: $\bold{\dfrac{x-7}{2}=5\qquad \rightarrow \qquad x = 17}$

<u>Step-by-step explanation:</u>

Monica has some cookies: x

She gave seven to her sister: x - 7

Then she divided the remainder into 2: $\dfrac{x-7}{2}$

She still had five cookies left: $\dfrac{x-7}{2}=5$

To solve, multiply both sides by 2, then add 7 to both sides.

$\dfrac{x-7}{2}(2)=5(2)\qquad \rightarrow \qquad x - 7 = 10$

$x - 7 = 10\qquad \rightarrow \qquad x = 17$

1. Take the 4x and add it to the 6x = 10x (always do x first, makes it easier)
2. Subtract 45 from -105 = -150
3. Divide 10 from -150 = -15
4. x is less than or equal to -15
