Deepak wants to simplify the equation and solve for x. He has been trying to use the distributive property, but he is not sure if he is doing it correctly.
Step 1: Use the Distributive Property to Simplify
The distributive property is a fundamental concept in algebra that allows us to multiply a single term by multiple terms. In this case, we can use the distributive property to simplify the equation.
The distributive property states that for any real numbers a, b, and c:
We can apply this property to the equation by multiplying the 4x and -3x terms by the 5/2 term.
Using the distributive property, we can rewrite the equation as:
Simplifying the equation, we get:
Step 2: Simplify by Combining Like Terms
Now that we have simplified the equation using the distributive property, we can combine like terms to make it easier to solve.
Like terms are terms that have the same variable raised to the same power.
In this case, we have two like terms: 4x and -3x. We can combine these terms by adding their coefficients.
So, the simplified equation is:
Step 3: Add 5 to Both Sides of the Equation
To isolate the variable x, we need to get rid of the constant term on the left-hand side of the equation. We can do this by adding 5 to both sides of the equation.
Adding 5 to both sides, we get:
Step 4: Simplify the Right-Hand Side of the Equation
Now that we have added 5 to both sides of the equation, we can simplify the right-hand side.
To add fractions, we need to have a common denominator.
In this case, the common denominator is 4. So, we can rewrite the equation as:
Simplifying the right-hand side, we get:
Step 5: Multiply Both Sides of the Equation by 2
To get rid of the fraction on the left-hand side of the equation, we can multiply both sides by 2.
Multiplying both sides by 2, we get:
Step 6: Subtract 5 from Both Sides of the Equation
To isolate the variable x, we need to get rid of the constant term on the left-hand side of the equation. We can do this by subtracting 5 from both sides of the equation.
Subtracting 5 from both sides, we get:
Step 7: Simplify the Right-Hand Side of the Equation
Now that we have subtracted 5 from both sides of the equation, we can simplify the right-hand side.
To subtract fractions, we need to have a common denominator.
In this case, the common denominator is 2. So, we can rewrite the equation as:
Simplifying the right-hand side, we get:
Step 8: Divide Both Sides of the Equation by 2
To solve for x, we need to get rid of the coefficient on the left-hand side of the equation. We can do this by dividing both sides by 2.
Dividing both sides by 2, we get:
The final answer is .
