A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the ...

Steps to solving Systems of Equations by Substitution: Isolate a variable in one of the equations. (Either y = or x =). Substitute the isolated variable in the other equation. This will result in an equation with one variable. Solve the equation. Substitute the solution from step 3 into another equation to solve for the other variable.

Learn how to use the Algebra Calculator to solve systems of equations. Example Problem. Solve the following system of equations: x+y=7, x+2y=11 ...

Well, if we know y, we can now solve for x. x is equal to 9 minus 2y. So let's do that. x is equal to 9 minus 2 times y, 2 times 7. Or x is equal to 9 minus 14, or x is equal to negative 5. So we've just, using substitution, we've been able to find a pair of x and y points that satisfy these equations.

Solving systems with substitution. Systems of equations with substitution: 2y=x+7 & x=y-4. Systems of equations with substitution. This is the currently selected item. Systems of equations with substitution: y=4x-17.5 & y+2x=6.5. Systems of equations with substitution: -3x-4y=-2 & y=2x-5.

The substitution method is a completely algebraic method for solving a system of equations. The substitution method requires that we solve for one of the variables and then substitute the result into the other equation.

Steps to solving Systems of Equations by Substitution: Isolate a variable in one of the equations. (Either y = or x =). Substitute the isolated variable in the other equation. This will result in an equation with one variable. Solve the equation. Substitute the solution from step 3 into another equation to solve for the other variable.
