Answer: -9/6
Step-by-step explanation:
Substitute the value of X and Y into the equation. Therefore
X-2y
When X = -1 and when Y= 4
-1-2(4)
-1-8=-9
Y-2x
When X= -1 and when Y=4
4-2(-1)
When multiplying 2 negatives it becomes a positive so...
4+2=6
-9,6 would be your answers... hope this helps you!!
Answer:
- 7/2 i'm pretty sure
Step-by-step explanation:
substitute x for - 1 and substitute y for 4.
x - 2y = - 1 - 2 (4)
y - 2x = 4 - (2 -1)
then do the math for both of them and it should either be -7/2 or 7/2
