If you would like to solve this expression, you can calculate this using the following steps:
1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
4 + 7 = 32
5 + 8 = 45
6 + 9 = 60
7 + 10 = 77
8 + 11 = 96
The correct result would be 8 + 11 = 96.
Answer:
x = 1
y = 6
Explanation:
The first given equation is:
-x + y = 5
Multiply this equation by -1, you will get:
x - y = -5 ............> I
The second given equation is:
4x + y = 10 ..........> II
Add the two equations I and II as follows:
x - y = -5
+ 4x + y = 10
..............................
5x = 5
Therefore:
x = 5/5
x = 1
Substitute with x in equation I to get y as follows:
x - y = -5
1 - y = -5
y = 1 + 5
y = 6
Hope this helps :)
X+y = 6
x-y = 2
Add both equations,
2x = 8
x = 4
Substitute it in equation 1,
4+y = 6
y = 6-4 = 2
In short, x = 4 & y = 2
Hope this helps!
