How do you solve an equation with the following?
Answer
- Given : Equations with single variable.
- To Find : Value of x.
- Solution: 1. ( x – 4)/7 – x = (5 – x)/3 + 1.
- => x = -68/11. 4. ( x + 4)² – (x + 5)² = 9.
- => x = -9. 9 . 2(3x + 2) = 154.
- => x = 25. 10 . 160 – 4x + 5x + 6x = 300.
- => x = 20. Learn more: solve the following linear equation by trial and error as well as by …

How do you tell if an equation is a solution?
Determine whether a number is a solution to an equation.
- Substitute the number for the variable in the equation.
- Simplify the expressions on both sides of the equation.
- Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.
What does simplify an equation mean?
Simplifying an expression is just another way to say solving a math problem. When you simplify an expression, you’re basically trying to write it in the simplest way possible. At the end, there shouldn’t be any more adding, subtracting, multiplying, or dividing left to do.

How do you find the work system of equations?
To check a system of equations by substitution, you plug your values for x and y into the original equations. If both simplified expressions are true then your answer is correct. Since x=2 and y=−3 worked for both equations I know that (2,−3) is the solution to this system of equations.
What are the four steps for solving an equation?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal.
What is the formula of substitution method?
The method of substitution involves three steps: Solve one equation for one of the variables. Substitute (plug-in) this expression into the other equation and solve. Resubstitute the value into the original equation to find the corresponding variable.
