Question

Solve these equations by finding the ordered pair. y= x - 5 and -x - 3y = 7

Answer 1

Given:

The equations y = x - 5 and -x - 3y = 7.

Required:

Solve equations by finding the ordered pair.

Explanation:

We will put y = x - 5 in -x - 3y = 7.

We will get,

$\begin{gathered} -x-3(x-5)=7 \\ -x-3x+15=7 \\ -4x=-8 \\ x=2 \\ \text{ Insert }x=2\text{ in }y=x-5 \\ y=2-5 \\ y=-3 \end{gathered}$

Ordered pair is (2, -3).

Answer:

The ordered pair equals (2, -3).
