Solving a One-Step Linear Equation Problem Type 1


Advertisements

In this type of problems, we use either only addition or subtraction operation to move the numbers and get the solution for the one-step equations.

Identify the solution to the linear equation 3 + x = −5

Solution

Step 1:

In this problem, we use subtraction to move the numbers and get the solution for the one-step equation.

3 + x = −5

Step 2:

Subtracting 3 from both sides of the equation to isolate the variable x.

3 + x – 3 = −5 – 3

So, x = −8

Identify the solutions to the linear equation −11 − y = 8

Solution

Step 1:

In this problem, we use addition to move the numbers and get the solution for the one-step equation.

−11 − y = 8

Step 2:

Adding 11 to both sides of the equation to isolate the variable y.

−11 – y + 11 = 8 + 11

– y = 19

Step 3:

Changing sign on both sides of the equation

So, y = − 19
