Question

How to solve two step equations

Answer 1

Answer:Step 1) Add or Subtract the necessary term from each side of the equation to isolate the term with the variable while keeping the equation balanced.Step 2) Mulitply or Divide each side of the equation by the appropriate value solve for the variable while keeping the equation balanced.

Step-by-step explanation:Beacause we want to achieve x=some number, which is called the solution to an equation.2x−12+12=5+122x=17Now since two is being multiplied with the variable x, we are going to apply the inverse operation of division to remove it.2x2=172x=172

Answer 2

Explanation:

An example of a two-step equation is:

2x + 3 = 13

Typically, in a two-step equation, there is a number multiplying a variable, and an additional number being added to or subtracted from the variable part.

In the example above, the variable x is being multiplied by 2.

Then, 3 is being added to the variable part, 2x.

Solving:

First undo the number being added or subtracted to the variable part by using the opposite operation.

In the example above,

2x + 3 = 13,

3 is being added to 2x, so use the opposite operation to addition which is subtraction.

Subtract 3 from both sides.

2x + 3 - 3 = 13 - 3

2x = 10

Now that you only have the product of a number and the variable, undo the operation, by applying the opposite operation. The variable x is being multiplied by 2, so do the opposite operation, which is divide both sides by 2.

2x/2 = 10/2

x = 5

The solution is x = 5.

Now we check:

2x + 3 = 5

Try x = 5.

2(5) + 3 = 13

10 + 3 = 13

13 = 13

Since 13 = 13 is a true statement, the solution x = 5 is correct.
