Solve the system below using elimination<br> {5x+9y= -10}<br> {7x+10y= -1}
bixtya [17]

∑Hey , jillianwagler ⊃

Answer:

x = 7, y = -5

Step-by-step explanation:

<u><em>Given~:</em></u>

<em>Solve the system below using elimination</em>

<em>{5x+9y= -10}</em>

<em>{7x+10y= -1}</em>

<u><em>Solve:</em></u>

<u><em></em></u>\begin{bmatrix}5x+9y=-10\\ 7x+10y=-1\end{bmatrix}

Isolate x ( 5x + 9y = -10 ) : \mathrm{x=\frac{-10-9y}{5}}

Substitute: \mathrm{x=\frac{-10-9y}{5}}

\begin{bmatrix}7\cdot \frac{-10-9y}{5}+10y=-1\end{bmatrix}

\begin{bmatrix}\frac{-70-13y}{5}=-1\end{bmatrix}

Isolate y : \frac{-70-13y}{5}=1:y=-5

Substitute: y=-5

x=\frac{-10-9\left(-5\right)}{5}=7

Hence, x=7

Therefore, the solution for \begin{bmatrix}5x+9y=-10\\ 7x+10y=-1\end{bmatrix} are:

x=7,\:y=-5

ehidna [41]

Answer:

B.  7√10.

Step-by-step explanation:

√40 = √4√10 = 2√10

√90 = √9√10 = 3√10

So √40 + 2√10 + √90

=  2√10 + 2√10 + 3√10

= 7 √10.
