Question

y = 1/2x – 6 x = –4 what is the solution to the system of equations? (–8, –4) (–4, –8) (–4, 4) (4, –4)

Answer 1

y = 1/2 (-4) - 6 = -2 - 6 = -8
Therefore, solution is (-4, -8)

Answer 2

Answer:

(-4,-8)

Step-by-step explanation:

Given :

$y = \frac{1}{2} x -6$  ---(1)

$x= -4$    ------(2)

Solution :

To find the solution of given system of equation we need to use the substitution method i.e. we need to substitute the value of x from equation (2)  in equation (1).

⇒$y=\frac{1}{2} *(-4)-6$

⇒$y=-2-6$

⇒$y= -8$

Thus for x =-4 we get y = -8

Hence (-4,-8) is the solution to the given system of equations .
