Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations.
Aleksandr-060686 [28]

Answer:

\huge \colorbox{red}{(x,y)=(-1,-3)}

Step-by-step explanation:

multiply first equation by 4 and second by 3 respectively:

\begin{cases} \displaystyle - 12x + 28y =  - 72 \\   \:  \: \displaystyle  \: 12x - 12y = 24 \end{cases}

combine the equations:

\underline{ \begin{cases} \displaystyle - 12x + 28y =  - 72 \\   \:  \: \displaystyle  \: 12x - 12y = 24 \end{cases}} \\  \displaystyle16y =  - 48

divide both sides by -48:

\displaystyle \:  \frac{16y}{16}  =  \frac{ - 48}{16}  \\ y =  - 3

substitute the value of y to the second equation

\displaystyle \: 4x - 4. - 3 = 8

simplify multiplication:

\displaystyle \: 4x  + 12 = 8

cancel 12 from both sides:

\displaystyle \: 4x =  - 4

divide both sides by 4

\displaystyle \:  \frac{4x}{4}  =  \frac{ - 4}{4}  \\ x =  - 1

therefore our solution is

\displaystyle (x,y)=(-1,-3)

Megan uses 2/3 cup of almonds to make 4 cups of trail mix. Using the same porportion,how many cups of almonds would Megan need t
Viktor [21]
Okay so let's make this fraction bigger. 2/3 x 2 would equal 4/6 which means megan uses 1/6 per cup of trail mix. so if she wanted to make 9 batches of trail mix she would use 2 1/6 but let's make that into an improper fraction.. aka 13/6 .. we cannot simplify that so megan would need 2 1/6 cups of almonds
