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
How many solutions does 2x-y equals 8 and x plus y equals 1 have?
2x - y = 8 x + y = 1 These are your two equations. They will have two solutions since you have two variables. The solutions are x=3 and y=-2
Solutions for 4x squared plus 4x plus 1 equals 0?
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
How many solutions do the equations 2x - y equals 8 and x plus y equals 1 have?
Only one: (3,-2)
What are the solutions to 2x2 5x 8 6?
I messed up the question I ment what are the solutions to 2x^2 + 5x + 8 = 6
What is 2x times x times y divided by 9 times y squared?
18
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 is the answer to 2 -1 y equals 2x-1?
There are infinitely many solutions. These are coordinates of all points on the line given by the equation 2 - y = 2x - 1 or 2x + y = 3.
How many solutions does an equation have when tthe variable adds out and the final sentence is false?
2(2x-1)+2x=6(x-1)

How many solutions are there to the following system of equations?2x - y = 2-x + 5y = 3if this is your question,there is ONLY 1 way to solve it.
How many solutions does 2x-y equals 8 and x plus y equals 1 have?
2x - y = 8 x + y = 1 These are your two equations. They will have two solutions since you have two variables. The solutions are x=3 and y=-2
What are the solutions of 2X 3 7?
x<-2 or x>1
How many solutions does the following system have x plus y equals 3 and 2x plus y equals 5?
It has 2 solutions and they are x = 2 and y = 1 which are applicable to both equations
What is the definition of infinite solutions?
3(4x*-2)=6(2x-1)
Solutions for 4x squared plus 4x plus 1 equals 0?
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
What is an identity in algebra?
It is when a variable has an infinite number of solutions Example: 2x + 2 = 4x divided by 2 +2
