Examine the system of equations -3x+y=4, -9x+5y=-1 what is the solution

serious [3.7K]

Answer: x=-7/2 y=29/2

Steps:

Use the elimination method

Multiply -3x+y=4 by 5 to make the coefficient next to the y in both equations the same

5(-3x+y=4)

-15x+5y=20

Then, subtract to eliminate the y

-15x+5y=20
- -9x+5y=-1

= -6x=21
Divide both sides by -6 to isolate x

= x= -7/2

Next substitute -7/2 into x in one of the equations

-3(-7/2)+y=4

-21/2+y=4

Add 21/2 from both sides to isolate y

y=29/2

Nancy left a bin outside in her garden to collect rainwater. She notices that 1 over 2 gallon of water fills 2 over 3 of the bin

MrRissso [65]

The entire bin can take up to 3/3, meaning, one whole, thus

$\bf \begin{array}{ccllll}
gallons&\textit{portion of whole}\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
\frac{1}{2}&\frac{2}{3}\\\\
x&\frac{3}{3}
\end{array}\implies \cfrac{\frac{1}{2}}{x}=\cfrac{\frac{2}{3}}{\frac{3}{3}}$

solve for "x"
