-2x - 2 = 4
-2x = 4 + 2
-2x = 6
x = 6/-2
x = -3
Check:
-2(-3) - 2 = 4
6 - 2 = 4
4 = 4

X - 3y equals -3 and -2x plus 6y equals 12 solution?
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
What is the solution to the system 2x-y equals 2 2x-y equals -2?
2x - y = 2 2x - y = -2 This system is inconsistent -- that is, there is no solution. To help see why, let Z = 2x - y and notice Z can't be 2 and -2 at the same time.
Why does 2x-3 equals 2x-5 have no solution?
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
Solution of the equation 2x plus 3 equals 7?
2x + 3 = 72x = 4x = 2
Is x equals 6 a solution to-2x-4 equals -8?
No because x = 2
X - 3y equals -3 and -2x plus 6y equals 12 solution?
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?

Why does 2x-3 equals 2x-5 have no solution?
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
Does y equals 2x - 4 and y equals 2x - 5 have a common solution?
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
What is the solution of 2x plus 4 equals 8?
x=2
Is 0 -2 a solution of 2x - 5y equals 10?
Yes it is!
What is the solution to -3 equals 2x plus 1?
x=-2
Solution of the equation 2x plus 3 equals 7?
2x + 3 = 72x = 4x = 2
Is x equals 6 a solution to-2x-4 equals -8?
No because x = 2
What is the solution to x2 plus 2x equals 410 the solution is between 7 and 8?
The answer is (3.5)2 plus (4)2 equals 410.
What is the solution for y equals -x and 2x-y equals 6?
-4
Does x plus 2 equals 2x?
It does if x=2. That's the solution of your equation.
