HELPPPPPP MEEEEE y=6x-1 and -2x-3y=-2 USING SUBSTITUTION

1 answer:

7 0

Answer:
x = 4
y =23

work:
plug in the value of Y to -2x-3y=-2. -2x - 3(6x-1) = -2
multiply 3 and the numbers in parenthesis. -2x -18x - 3 =-2
combine like terms (-2x -18x). -20x - 3 = -2
subtract 3 from both sides to isolate the variable. -20x = -5
divide to isolate the variable (-20/-5) x = 4
-
now that we know the value of x, it'll be easy to find Y.
Plug it in to the first equation.
y=6(4)-1
y = 24 - 1
y = 23

so x = 4
and y = 23

hope this helps! :D

the time it takes to fill a water tank varies inversely with the water rate of the hose. At 8 gallons per minute, a hose can fil

$\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby

-------------------------------\\\\
\textit{time it takes to fill a tank varies inversely with the water rate}\\\\
t=\cfrac{k}{w}\quad 
\begin{cases}
t=\textit{time to fill}\\
w=\textit{water rate}
\end{cases}$

$\bf \textit{we also know that }
\begin{cases}
w=\stackrel{g/min}{8}\\
t=\stackrel{min}{45}

\\\\\\
therefore\qquad \boxed{t=\cfrac{360}{w}}

\textit{now if w = 15, what is \underline{t}?}\qquad t=\cfrac{360}{15}$
