Understanding the Base Components of the Expression
To tackle the equation (x5)x (1×2)=20, we must break it down into simpler parts. The equation consists of two main components: (x5) and (1×2). Let’s examine what these components mean.
Defining the Variables
1. **Understanding ‘x’:**
– The letter ‘x’ often serves as a variable in mathematics. Variables represent unknown numbers that we need to determine.
2. **Understanding ‘5’:**
– The number 5 is a constant. It remains the same and serves as a multiplier to the variable ‘x’.
3. **Understanding ‘1×2’:**
– In this part, we see a multiplication scenario where 1 is multiplied by 2. This operation gives us a clear number: 1 x 2 = 2.
Now, substituting back into the equation, we have:
\[ (x5) \cdot 2 = 20 \]
This gives us a clearer picture of the equation we need to solve.
Solving the Equation
Now that we understand the terms, it is time to solve for ‘x’. Let’s express the equation step by step.
1. **Rearranging the Equation:**
– From our earlier substitution, we rewrite our equation:
\[ (5x) \cdot 2 = 20 \]
2. **Simplifying:**
– Next, we simplify the left side by multiplying:
\[ 10x = 20 \]
3. **Dividing by 10:**
– To isolate ‘x’, we divide both sides by 10:
\[ x = \frac{20}{10} \]
4. **Finding the Value of ‘x’:**
– Thus, we find that:
\[ x = 2 \]
So, the number that fits into our original expression is 2.
Checking Our Work
It’s always important to check our calculations. Let’s substitute ‘x’ back into the original equation to verify our solution.
1. **Plugging ‘x’ back into the equation:**
– We have:
\[ (2 \cdot 5) \cdot (1 \cdot 2) = 20 \]
2. **Calculating the left side:**
– Simplifying:
\[ 10 \cdot 2 = 20 \]
Both sides of the equation equal 20, confirming that our solution is correct!
Exploring Similar Equations
Now that we’ve solved (x5)x (1×2)=20, let’s explore similar equations to strengthen our understanding and skills.
Example Equation 1: (x3)x (2×3)=18
1. **Breaking It Down:**
– Similar to our previous equation, we identify the components:
– Here, we have 3 as a multiplier for ‘x’ and (2×3) simplifies to 6, leading to:
\[ (3x) \cdot 6 = 18 \]
2. **Solving:**
– Simplifying gives us:
\[ 18x = 18 \]
\[ x = 1 \]
Example Equation 2: (x4)x(3×2)=24
1. **Breaking It Down:**
– The components are identified as:
\[ (4x) \cdot 6 = 24 \]
2. **Solving:**
– Simplifying gives us:
\[ 24x = 24 \]
\[ x = 1 \]
Each of these equations demonstrates a similar structure to our initial equation, allowing for practice in solving for ‘x’ across various multiples.
