how can you specify what the variable stand for, write and equation, and solve this problem. a sewing project requires material costing $44 plus some tassels. if the material and tassels are to be purchased with four $20 bills, how many tassels can be purchased if they cost $2.40 each?
You need to be sure the variable denominator does not become zero, where the equation would not be defined.
It is a linear equation in two unknown variables, y and c. One linear equation in two unknowns cannot be solved, it can only be arranged so that one or the other variable is the subject of the equation. However, that requires you to identify which variable is to be made the subject of the equation.
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.
you have to solve the actual equation in order to answer this about your variable
substitution
You need to be sure the variable denominator does not become zero, where the equation would not be defined.
A two-step equation is a mathematical equation that requires two steps to solve. It involves applying inverse operations to isolate the variable on one side of the equation. The goal is to determine the value of the variable that satisfies the equation.

It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.It appears to be a linear equation in the variable, g.
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
Simultaneous equation* * * * *No, simultaneous equations are two or more equations that have all to be true at the same time (simultaneously) for the solution.An equation with more than one variable is a multivariate equaion.Area = 0.5*Length*Height or a = 0.5*l*h for the area of a triangle has more than one variables, but it is certainly not simultaneous.An equation with a variable is called a single variable equation. An equation that has more than one variable is called as a multi-variable equation. A polynomial equation has one variable in different powers: a common example is quadratic equations.

linear equation in one variable
A two-step equation is an equation that requires two steps to solve We must eliminate any constant that is on the same side as the variable first To solve, use the inverse operations to isolate the variable by itself Remember whatever you do to one side, you must do to the other
It is to make the variable the subject of the equation.
