That's exactly the purpose of the substitution method ... to get an equation with
one less variable. When you have it, you solve it for the variable that's left.

Which is most likely the first step in solving a system of nonlinear equations by substitution APEX?
Isolating a variable in one of the equations.
What is usually the first step in solving a system of nonlinear equations by substitution?
The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.
How is solving a two step equation like solving one step equation?
the alikes of solving a one-step or two-step equation: in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other alike is to have the number in front of the variable equal to one the variable does not always have to be x. These equations can use any letter as a variable.
What does the word variable mean in mathematics?
A number that one is solving for-the unknown.
What are steps in practical problem solving?
Which of the following are steps in practical problem solving? Assign an identifying variable to the quantity to be found. Make a guess at the value of the variable. Write a sentence stating conditions placed on the quantity. Check if the value is correct. Solve the sentence for the variable.
How do use substitution when solving system of equations?
You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.
Which is most likely the first step in solving a system of nonlinear equations by substitution APEX?
Isolating a variable in one of the equations.
Why is substitution the best method in solving systems of equations?
It is not always the best method, sometimes elimination is the way you should solve systems. It is best to use substitution when you havea variable isolated on one side
What is the first step in solving a 2step equatioin?
Add the inverse to both sides of the equation to get the variable term by itself. ex: 3x + 7 = -8 Add -7 to both sides of the equation this 'cancels' the +7 on the left leaving 3x, the variable term, alone on the left.
What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
Solving for given variable?

What is usually the first step in solving a system of nonlinear equations by substitution?
The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.
Is the goal in solving an equation to get the variable by itself?
Yes
