Without an equality sign the given expression can't be considered to be an equation
The answer is....... 1. read the problem 2. determine the unknowns and represent them 3. write an equation 4. solve the equation 5. answer the question
You write it as an equation, and then solve the equation.
The answer depends on what the problem is. The given information allows you to form one equation, which is: 2y = 3b, where b and y have obvious definitions.
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.
Instead of just giving you the answer, I'll tell you how to solve the problem. To solve this problem, write two equations. Let one variable be x and the other y. Then you can say: xy = 800 x + y = -70 Isolate x + y = -70 for y and you get y = -70-x Then plug it back into the first equation, solve for x and plug your answer into the second equation to solve for y. Hope that helps, and let me know if you have any questions :)

To write an equation for a given problem, first identify the unknown quantity you want to find. Then, use variables to represent the unknowns and write an equation that relates the known quantities to the unknown quantity. Solve the equation to find the value of the unknown.

4 x .25 = 1
You do not need to write anything to calculate things mentally.
I would gingerly perform the step, write the solution,and go on to the next problem.
write and solve an equation to find the value of x. 8x plus 35 and then 14x-7

You can draw a flowchart of solving a particular problem and then write a program to solve that problem.
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
whatever the equation is write the equation in words then solve each step in a sentence.
