Step-by-step explanation:

To eliminate y we multiply first equation by 4 then add it to the second equation :

4 × (x+y)=2 ➡ 4x + 4y = 8
4x + 4y + 3x -4y = 8 + 27 ➡7x = 35 ➡x = 5
Replace x with the value we found to calculate the value of y : x +y = 2➡5+y = 2 ➡y = -3

Solve for U 11=8+u/7.68

BlackZzzverrR [31]

$\begin{gathered}\\ \sf\longmapsto 11=\frac{8+u}{7.68}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11 = \frac{8 + u}{ \frac{192}{25} } \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11=\frac{(8+u)×25}{192}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11=\frac{200+25u}{192}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 2112=200+25u\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 2112-25u=200\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -25u=200-2112\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -25u=-1912\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto u=\frac{1912}{25}\end{gathered}$

Alternate form:

u=76.48
