4x+11y=7 4x+3y=-1 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
