I hope this helps u for the test next week good luck
Answer:
x = -2 and y = 1
Step-by-step explanation:
→ Rearrange x - y = -3 to make y the subject
-y = - x - 3 so y = x + 3
→ Substitute into 2x + y = -3
2x + x + 3 = -3
→ Simplify
3x + 3 = -3
→ Minus 3 from both sides
3x = -6
→ Divide both sides by 3
x = -2
→ Substitute x value into first equation
-4 + y = -3
→ Add -4 to both sides
y = 1

Answer:
D
Step-by-step explanation:
Angle 5 is equal to angle 8 because the two angles are an alternate interior angle. We already know that angle 7 and 8 are supplementary because it's adjacent to each other on a straight line. So, since angle 5 and 8 is equal to each other, angle 5 is also supplementary to angle 7.
