To solve the equation \(5(2x + 2) - 4 = 2x + 6\), we can start by expanding and simplifying both sides.
1. **Expand the left side**:
\[
5(2x + 2) - 4 = 10x + 10 - 4 = 10x + 6
\]
2. **Rewrite the equation**:
\[
10x + 6 = 2x + 6
\]
3. **Subtract \(2x\) from both sides**:
\[
10x - 2x + 6 = 6
\]
This simplifies to:
\[
8x + 6 = 6
\]
4. **Subtract 6 from both sides**:
\[
8x = 0
\]
5. **Divide by 8**:
\[
x = 0
\]
Now we check the solution:
Substituting \(x = 0\) back into the original equation:
Left side:
\[
5(2(0) + 2) - 4 = 5(0 + 2) - 4 = 5 \cdot 2 - 4 = 10 - 4 = 6
\]
Right side:
\[
2(0) + 6 = 0 + 6 = 6
\]
Both sides equal 6, confirming that our solution \(x = 0\) is correct.
Since we found one unique solution, the answer is:
**The equation has one solution: x=0.**
1. **Expand the left side**:
\[
5(2x + 2) - 4 = 10x + 10 - 4 = 10x + 6
\]
2. **Rewrite the equation**:
\[
10x + 6 = 2x + 6
\]
3. **Subtract \(2x\) from both sides**:
\[
10x - 2x + 6 = 6
\]
This simplifies to:
\[
8x + 6 = 6
\]
4. **Subtract 6 from both sides**:
\[
8x = 0
\]
5. **Divide by 8**:
\[
x = 0
\]
Now we check the solution:
Substituting \(x = 0\) back into the original equation:
Left side:
\[
5(2(0) + 2) - 4 = 5(0 + 2) - 4 = 5 \cdot 2 - 4 = 10 - 4 = 6
\]
Right side:
\[
2(0) + 6 = 0 + 6 = 6
\]
Both sides equal 6, confirming that our solution \(x = 0\) is correct.
Since we found one unique solution, the answer is:
**The equation has one solution: x=0.**
