Answer:
Well elimination is basically multiplying a number to make it possible for it to cancel out
We can multiply the first equation by 2
2(x+2y=-1)
This would be
2x+4y=-2
Its still the same thing but just with non simplified numbers
We can now do any method really to solve
I will just do the subtraction method
2x+4y=-2
-2x+y=4
Solve
2x-2x=0
4y-y= 3y
-2-4= -6
3y= -6
Now solve
y=-2
To find x subsitute in “y” and find ”x”.
x+2*-2=-1
x-4=-1
x=3
y= -2
x= 3

Answer:
Jamie is currently 15.
Step-by-step explanation:
Answer: x = 32 y = 20
Step-by-step explanation:
114 = 3x + 18 114 = 3(y + 18)
-18 - 18 /3 /3
= =
96 = 3x 38 = y + 18
/3 /3 -18 -18
= =
32 = x 20 = y
