How to solve 2x 6 3?
How to solve 2x + 6 = 3?
To solve a linear equation like 2x + 6 = 3, we need to isolate the variable x. This means we want to get x on one side of the equation and all other terms on the other side.
Step 1: Subtract 6 from both sides of the equation to move the constant term to the other side.
2x + 6 - 6 = 3 - 6
2x = -3
Step 2: Divide both sides of the equation by 2 to solve for x.
2x/2 = -3/2
x = -3/2 or x = -1.5
Conclusion: The solution to the equation 2x + 6 = 3 is x = -1.5 or x = -3/2.
Remember, when solving linear equations, it is important to apply operations to both sides of the equation to maintain its equality. By following these steps, you can easily solve similar equations and find the value of the variable x.
How to solve 2x 6 20?
When faced with an equation like 2x + 6 = 20, it is important to determine the value of 'x' that will make the equation true. To solve this equation, follow these steps:
Step 1: Start by isolating the variable 'x' on one side of the equation. To do this, subtract 6 from both sides: 2x + 6 - 6 = 20 - 6.
Step 2: Simplify the equation: 2x = 14.
Step 3: To solve for 'x', divide both sides of the equation by the coefficient of 'x', which is 2: 2x/2 = 14/2.
Step 4: Simplify further: x = 7.
Therefore, the solution to the equation 2x + 6 = 20 is x = 7.
Remember to always check your solution by substituting the value of 'x' back into the original equation to ensure it is correct. In this case, plugging in x = 7 should yield a true statement: 2(7) + 6 = 20. And indeed, when we simplify, we get 14 + 6 = 20, which is true.
By following these steps, you can solve equations with the variable 'x' and find the value or values that satisfy the equation.
How do you solve the equation 2x 6 12?
To solve the equation 2x + 6 = 12, we need to isolate the variable x. Here are the steps:
Step 1: Subtract 6 from both sides of the equation to get rid of the constant term on the left side.
2x + 6 - 6 = 12 - 6
2x = 6
Step 2: Divide both sides of the equation by 2 to solve for x.
2x/2 = 6/2
x = 3
Therefore, the solution to the equation 2x + 6 = 12 is x = 3.
What is the correct answer to 3 3 * 6 2?
The question: What is the correct answer to 3 3 * 6 2?
The question is asking for the correct answer to the equation 3 multiplied by 3, then multiplied by 6, and finally multiplied by 2.
Order of operations: To solve this problem correctly, we need to apply the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Parentheses: There are no parentheses in the given equation.
Exponents: There are no exponents in the given equation.
