To solve the equation \(32(4 - 8x) + 5x = 1 - 7x\), let's take it step by step!
Step 1: Distribute
First, we need to use the distributive property on \(32(4 - 8x)\). This means we multiply \(32\) by both \(4\) and \(-8x\):
\[ 32 \cdot 4 - 32 \cdot 8x + 5x = 1 - 7x \]
Calculating that gives us:
\[ 128 - 256x + 5x = 1 - 7x \]
Step 2: Combine like terms
Now, let's combine the \(x\) terms on the left side. We have \(-256x + 5x\):
\[ 128 - 251x = 1 - 7x \]
Step 3: Get all \(x\) terms on one side
To move all the \(x\) terms to one side, we add \(7x\) to both sides of the equation:
\[ 128 - 244x = 1 \]
Step 4: Isolate the constant
Next, we want to isolate \(x\). First, subtract \(128\) from both sides:
\[ -244x = -127 \]
Step 5: Solve for \(x\)
Finally, we divide both sides by \(-244\) to find \(x\):
\[ x = \frac{127}{244} \]
Conclusion
The solution we found is \(x = \frac{127}{244}\). That means there is 1 unique solution!
