Since you already have y isolated on one equation it's easy. Plug in 3x-11 as for for the second equation. Solve and find what x equals. Then plug the x into the first equation to find y. Hope this helps!

\begin{cases}
 y=\boxed{3x-11}\\
 y- 3x=-13\\
------\\
\boxed{3x-11}- 3x=-13
\end{cases}

solve for "x"

The width of rectangular solid is 20ft, which is 4/5 of its length. The height of it is 2/9 of the sum of the length and width.
lilavasa [31]
Let L and H represent length and height, respectively.
.. 20 ft = (4/5)*L
.. L = (5/4)*(20 ft) = 25 ft . . . . . . . . multiply by the reciprocal of the coefficient of L

.. H = (2/9)*(L +20 ft)
.. = (2/9)*(25 ft +20 ft))
.. = (2/9)*(45 ft) = 10 ft

The volume is the product of length, width, and height.
.. V = (25 ft)*(20 ft)*(10 ft) = 5000 ft^3

1). Arrow starting with a solid point from x = -2                   x ≤ -2

directing towards negative numbers of x                                                         2).Arrow starting with a hollow circle from x = 2                 x >2  

directing towards positive numbers of x

3). Arrow starting with a hollow circle from x = 2                x < 2 ⇒ x - 2 < 0  

directing towards negative numbers of x

4). Arrow starting with a solid circle from x = 2                   x ≥ 2 Or 2 ≤ x

directing towards positive numbers of x

5). Arrow starting with a hollow circle from x = -2                   x > -2

directing towards positive numbers of x
