$( - 6 + 4x) + 6 = 9 + 6 \\ 4x = 15$

divide all sides by 4:

$\frac{4x}{4} = \frac{15}{4} \\ \\ { \underline{ \underline{x \: \: is \: \: \frac{15}{4} }}}$

frozen [14]

Answer:

6x + 12y

Step-by-step explanation:

Using distributive property means multiplying the number outside of the parentheses to each individual number within the parentheses:

3 × 2x = 6x

3 × 4y = 12y

Since there is an addition sign within the parentheses, we add these two numbers together. However, they are not like terms so their sum cannot actually be calculated
