Solve the simultaneous equation of x+y=8 and x-y=2

Answer 1

To solve this system of equations, we can add the two equations together:

x + y + x - y = 8 + 2
2x = 10
x = 5

Now that we have found the value of x, we can substitute it back into one of the original equations to solve for y:

5 + y = 8
y = 8 - 5
y = 3

Therefore, the solution to the simultaneous equations x + y = 8 and x - y = 2 is x = 5 and y = 3.
