Answer:
B
Step-by-step explanation:
-5x = y - 5 (1)
-2y = -x - 21 (2)
Change x to the left hand side of equation (2)
x = 2y - 21 (3)
Multiply (1) by 2 times:
-10x = 2y - 10 (4)
Use (4) - (3)
-10x = 2y - 10
- x = 2y - 21
-11x = -10 + 21
-11 x = 11
x = -1
Apply x = -1 in (1)
-5*(-1) = y - 5
5 = y-5
y = 5+5
y = 10
So x = -1
y = 10
Hope this help you :3
Answer:
