How many solutions does each system have?
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

How do you determine how many solutions a discriminant has?
The discriminant is the formula b squared minus 4ac remembering that a, b and c are the coefficients of your quadratic in standard form. It tells you the number of solutions to a quadratic equation. If the discriminant is greater than zero, there are two solutions.
How do you find the solution to x2+3x+2?
To find equation solutions, solve x+1=0 and x+2=0. To find equation solutions, solve x+ 1 = 0 and x+ 2 = 0. x2+3x+2=0 Two solutions were found : x = -1 x = -2 Step by step solution : Step 1 :Trying to factor by splitting the middle term 1.1 Factoring x2+3x+2 The first term is, x2 its
Are there any complex solutions for the equation 2x = -1?
Yes there are. There are infinitely many complex solutions for the equation 2^x = -1, in fact! We first rewrite 2^x=-1 as (e^ {\\ln 2})^x = e^ {x\\ln 2}=-1. Now e^ {ix} = \\cos x + i\\sin x, Yes there are. There are infinitely many complex solutions for the equation 2x = −1, in fact! We first rewrite 2x = −1 as (eln2)x = exln2 = −1.
What is the value of X with infinite solutions?
An equation with infinite solutions means X = All real numbers. So, you would be able to pick any number for X and the equation would be true. This doesn’t work for you equation. If x=13, then the only value that is a valid solution is 13.
How do you know if two equations have exactly one solution?
If the two equations are in standard form (both variables on one side and a constant on the other side), then the following are true: 1) lf the ratio of the coefficients on the x’s is unequal to the ratio of the coefficients on the y’s (in the same order), then there is exactly one solution.
