4x+11y=7<br><br>4x+3y=-1<br>what are the steps
andreev551 [17]

Answer:

x = -1, y = 1

Step-by-step explanation:

Given that:

\begin{bmatrix}4x+11y=7\\ 4x+3y=-1\end{bmatrix}

Isolate x for 4x + 11y = 7 which ⇒ x=\frac{7-11y}{4}

Substitute x=\frac{7-11y}{4} into the equation: which is:

\begin{bmatrix}4\cdot \frac{7-11y}{4}+3y=-1\end{bmatrix}

Drop Down to:

\begin{bmatrix}7-8y=-1\end{bmatrix}

Isolate y for 7-8y = -1: y = 1

Thus, x=\frac{7-11y}{4}

Substitute y = 1

Hence,

x=\frac{7-11\cdot \:1}{4}=-1

Solution ⇒ x = -1 and y = 1
