Question

8x+y=-16 and -3x+4=-5

Answer 1

Answer:

The values of x and y in the given system of equations are x=3 and y=-40

The solution to the given system of equations is (3,-40)

Step-by-step explanation:

Given equations are $8x+y=-16\hfill (1)$

ans $-3x+4=-5\hfill (2)$

To solve the given equations :

From equation (2)

$-3x+4=-5$

$-3x+4-4=-5-4$

$-3x=-9$

$x=\frac{9}{3}$

Therefore x=3

Now substitute the value of x=3 in the equation (1) we get

8(3)+y=-16

24+y=-16

24+y-24=-16-24

y=-40

Therefore the values of x and y in the given system of equations are x=3 and y=-40

The solution to the given system of equations is (3,-40).
