2x - 17 = 35
To write an equation that includes the keyword "how to write an equation," you can use a variable like x to represent the phrase. For example, the equation could be x "how to write an equation."
The equation for the sublimation of ammonium chloride is NH4Cl(s) -> NH4Cl(g).
You cannot write the quotient itself as an equation, but you can express a division operation and use an equation to express that the result of this operation (the quotient) is a specific value. For example, 16/8 =2.
find the variable(s). then write the equation(s). finally simplify the equation(s)
To write an equation, you use symbols and numbers to show a relationship between two or more quantities. The equation typically includes variables, which are represented by letters, and mathematical operations like addition, subtraction, multiplication, and division.
You write an equation that involves an independent variable (for example "x"), a dependent variable (for example "y"), and the first derivative, or higher-level derivatives, of the dependent variable (for example, dy/dx).
Cost = Fixed + (variable x units)
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.
Read the problem. Write each fact as a variable expression. Write each fact as a sentence.
1/2x=4
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
An example of a quadratic equation is ( ax2 bx c 0 ), where ( a ), ( b ), and ( c ) are constants and ( x ) is the variable.
