1. Answer below
The problem asks us to solve for , so that means we need to get
on one side of the equation by itself. To do so, we will need to divide both sides of the equation by
:
2. Answer below
The problem asks us to solve for , so that means we need to get
on one side of the equation by itself. To do so, we will need to add
to both sides of equation:
The solution of the system of equation is (-7, -2).
<h2>Given</h2>The system of the equations;
From equation 1
Substitute the value of y in equation 1
The value of x= 2 is rejected because x = 2 not satisfy the equation.
Substitute 2 for the value of x in equation II
y − x = 5
y – 2 = 5
y = 5 +2
y = 7 (x =2, y =7) … Not included in the options
If x = -7
Substitute the value of x = -7 in the equation
Hence, the solution of the system of equation is (-7, -2).
