Answer:

1 - (7 - 4x) = 9 \\ 1 - 7 + 4x = 9 \\  - 6 + 4x = 9

and 6 to either sides:

( - 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} }}}

3(2x+4y) distributive property review just need an answer like 5c+15
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

6x + 12y
