I am just not getting this, please explain. In each of the following system of equations, look at the system and determine whether it has infinitely many solutions, no solution, or one solution. Explain in each case how you came to your conclusion. You should not attempt the solve any of the You should not attempt the solve any of the systems. Are you sure you want to delete this answer? A system of equations means you have two lines on a graph. A solution is where the two lines cross. If the slopes are the same but the intercepts are different, they are parallel lines and they never cross.
If the slopes are different there is exactly one point where they cross. Equations of higher order may have more solutions, or none. Slopes are the same but intercepts are different. These are parallel lines that never cross. These lines cross so there is exactly one solution. This step allows you to state the value of one variable in terms of the other variable.
The second step is to substitute the value of x in Equation A for x in Equation B. This transforms Equation B into a 1-variable equation, which allows you to solve for the numeric value of that variable y. Graphically, this means that the lines representing the two equations intersect at that point. Science homework can be confusing, especially when it involves math formulas and equations. Students who have difficulties with their science homework can find homework help online through educational websites.
In the fourth grade, math integers, variables, symbols and parentheses are used in equations called mathematical expressions. Keep reading to find out ways that you can help your child master these new math concepts and techniques at home.
The Substitution Method The first step in using the substitution method is to solve one of the equations for one of the variables. Did you find this useful? If so, please let others know!

What are the three methods for solving systems of equations? Do they all produce the same answer? Which method do you prefer to use and why? Create 1 system of equations and ask your peers . Solving Systems of Equations with One Variable. Suppose that a system of two equations has one variable in common, such as x + 2 = 3 and 2x + 10 = To see if the systems have a solution in common, solve one of the equations and use substitution to solve the other.
