Answer:
infinite solutions
Explanation:
First multiply the parentheses by 2, and on the other side add similar terms
2(x + 5) = 1 + 2x + 9
2x + 10 = 2x + 10
Now we group all the x on the left side of the equation and the numbers on the right side
2x + 10 = 2x + 10
2x -2x = 10 - 10
0 = 0
This means than the equation has infinite solutions.
