Write your answer as an ordered pair. y = -3 + 5x 3x - 8y = 24
to come up with the total
The answer depends on what the percentage problem is. The equations will be different depending on whether you want to find:one number as a percentage of another,a given percentage of a number,the percentage change applied to a given number,find the original number if given the number after the percentage change.
Read the problem, make sure that you understand all questions. Draw the diagram. Mark all given values. Write Newton's equations using given values. Resolve the values in question.
You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.
If there are two variables, you'll usually need two equations in the two variables, to be able to find a specific solution. How you write the equation depends on the specific problem. In general, it requires some practice, to be able to convert a word problem into mathematical equations.

if y = xa then a = logxy
Write each equations in popular form. ... Make the coefficients of one variable opposites. ... Add the equations ensuing from Step two to remove one variable. Solve for the last variable. Substitute the answer from Step four into one of the unique equations.

2L + 2W = 34 L + W = 17 L = 2W - 4 3W - 4 = 17 3W = 21 W = 7 L = 10
Equations are never parallel, but their graphs may be. -- Write both equations in "standard" form [ y = mx + b ] -- The graphs of the two equations are parallel if 'm' is the same number in both of them.
IF they are math related, write appropriate equations and then apply math rules to solve the equations.
They are used to write balanced chemical equations.
