Given:
x + y = 5
2x + y = 6
We can subtract the second equation from the first to get:
-x = -1
x = 1.
From there, substituting back in to the first equation yields:
1 + y = 5
y = 4.
The solution is (1, 4).
x = -5
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2

It is a linear equation in x. The equation has the solution x = 0.
The value 6.5 does.
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
The solution is:- x = 0 and y = 5
