2x - 3 - 8 = 1. 2x - 11 = 1. 2x = 12.x = 6!

The solution is: x = 1 and y = -1

y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)

x=-2

The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2

Not sure what you mean; that equation certainly has a solution.

2x plus 3y

5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2

If by that you mean x= 1 and y= 2 then yes (1,2) is a solution

No. -4 does not equal -2(1).

Using the quadratic formula, you get the complex answers of 1 + 2i and 1 - 2i

2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
