Answer 1

Answer:

(-4, 1)

Step-by-step explanation:

-x-3=y, therefore x = -y-3

-3x - 8y = 4

Find the value of y

Substitute the x in -3x - 8y = 4 with -y-3

We get

-3·(-y-3) - 8y = 4

3y + 9 - 8y = 4

-5y = 4-9

-5y = -5

y = 1

_______________

x = -y-3

x = -1-3

x = -4

Answer 2

Answer:

Ok Here:

Step-by-step explanation:

STEP BY STEP

Substitution:

-x-3=y

-3x-8y=4

Solve for X                Substitute for Y

-3x-8(-x-3)=4                     -(-4)-3=y

-3x+8x+24=4                        4-3=y

5x+24=4                                y=1

    -24

5x=-20

5/5 = -20/5

x=-4

Solution: (-4,1)
