Answer 1

Ok Here:

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)

Answer 2

(-4, 1)

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

_______________

Find the value of x

x = -y-3

x = -1-3

x = -4

_______________

Answer (x, y) =
