Normally, I would go through the entire procedure to work out the answer for such an equation, but it is a bit awkward in this case. The first step in this equation would be to subtract 4 from each side, leaving us with 2x=0. Obviously, x is therefore 0 as well.

How many solutions does x plus y equals 4 and 2x plus 2y equals 8 have?
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
If x equals 4 then 2x plus 7 equals?
If x=4 then 2x+7 =
What is the answer to 2x plus 5 plus x2x-1 plus 2x plus 4?
x equals 4
What is the solution of the following system of equations y equals x plus 4 y equals -2x plus 1?
There are two solutions and they are: x = -1 and y = 3
What are the solutions to -x squared plus 2x plus 4 and x-2?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.

What are the solutions to -x squared plus 2x plus 4 and x-2?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
How many solutions does 2x plus y equals 5 and 2x plus y equals 4 have?
None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
3x plus 56 equals 2x plus 4?
3x+56 = 2x+4 3x-2x = 4-56 x = -52
How many real solutions are there in the equation 2x2 plus 2x - 4 equals 0?
0 = 2x^2 + 2x - 4 = 2(x^2 + x - 2) = 2(x-1)(x+2) Thus, there are two real solutions: x = 1 and x = -2
What are solutions for x2 plus 10x plus 1 equals -12 plus 2x?
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
2x plus 3 equals x plus 4?
Do you need this equation factored or? 2x+3=x+4?
-2x plus 4-8 equals 4?
x=-4
