Answer:
one solution.
Step-by-step explanation:
The given equation is |x+7|=0
When we eliminate the absolute sign then we'll get below two equations
x + 7 = 0 and x + 7 = -0
Let us solve these two equations.
x + 7 = 0
Subtract 7 to both sides
x = -7
Now, solve the second equation
x + 7 = -0
Subtract 7 to both sides
x = -0-7
x=-7
Therefore, the solution is x = -7 and hence, we can conclude that the equation |x+7|=0 have only one solution.
