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
What is the answer to 2x plus 5 plus x2x-1 plus 2x plus 4?
x equals 4
If x equals 4 then 2x plus 7 equals?
If x=4 then 2x+7 =
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.
How many solutions does 2x plus y equals 5 and 2y plus x equals 4 have?

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
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.
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.
3x plus 56 equals 2x plus 4?
3x+56 = 2x+4 3x-2x = 4-56 x = -52
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?
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
2x plus x plus 4 plus 2x equals x plus 20?
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
