-x-3y=-3
-2x-5y=-8
a.| -3 -3 |
|_ -8-5_|=-2
-1
b.| -3 -3 |
|_-8-5_|=9
-1
c.| -1 -3 |
|_-2 -8_|=-2
-1
d.| -1 -3 |
|_-2-8_|=9
-1

I think. It's your answer b.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
