Answer:
x=2, y=1
Step-by-step explanation:
Add:
2x+4y=8
+10x-4y=16
------------------
12x=24
Divide by 12 on both sides:
x=2
Substitute x with 2 on either 2x+4y=8 or 10x-4y=16 it doesn't matter it will result in the same answer.
(I will do both of them to prove it but you only need to replace x with one of the equation)
For 2x+4y=8
2(2)+4y=8
4+4y=8
Subtract 4 on both sides
-4+4+4y=8-4
4y=4
Divide 4 on both sides:
y=1
For 10x-4y=16
10(2)-4y=16
20-4y=16
-20+20-4y=16-20
-4y=-4
Divide -4 on both sides:
y=1
The answer for both 2x + 4y = 8 and 10x – 4y = 16 are the same showing that it doesn't matter which equation you replace the number with it will still result you in the same answer
Hope this helps!
