If you had 4x+5=20, first subtract 5 from each side. Since it was added, you have to do the opposite function. If it was minus 5 then you'd add.
Write it out like this: 4x+5-5=20-5
Solve so you get: 4x=15
Now all you have to do is divide both sides by 4, since you multiplied and that's the number by x.
4x/4=15/4
Solve: x=3.75
(Note: a number with x divided by that number will always equal x, or whatever variable you have.)

Compare the symbolic method for solving linear equations to the methods of using a table or graph?
Equations = the method
What are 3 methods to solving a system of linear equations?
u can use gauss jorden or gauss elimination method for solving linear equation u also use simple subtraction method for small linear equation also.. after that also there are many methods are available but above are most used
What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
How does solving a literal equation differ from solving a linear equation?
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
What is a method for solving a system of linear equations in which you multiply one or both equations by a number to get rid of a variable term?
It is called solving by elimination.
How do you solve a linear equation using the symbolic method?
you cant

What are the steps in comparison method in solving linear equation?
You drink lots of beer and get really drunk. At that point, you won't need to solve it, dick.
Why do you clear decimals when solving a linear equation?
because you just do!
How do you graph a linear equation slope intercept?
You can graph a linear equation slope intercept by solving the equation and plugging in the numbers : y=mx+b
How does the bisection method work when solving nonlinear equations?
it works exactly the same as it does with linear equations, you don't need to do any differentiation or anything fancy with this method, just have to plug in values of x, so it shouldn't make a difference if the equation is linear or nonlinear.
What are advantages to using the table method when graphing a linear equation?
For a linear I can see no advantage in the table method.
What does it mean when the result of solving a linear equation is x equals 0?
Solving a one variable linear equation involves getting the variable on one side of the equals sign by itself. To do this one uses the properties of numbers.
Why is it the graphing method is the least reliable method in solving system of linear equations?
