Q. How many solutions does this equation have?−h+10=−hChoices:(A)no solution(B)one solution(C)infinitely many solutions
Analyze the equation: Analyze the equation –h+10=–h. We want to find out if there are any values of h that make this equation true.
Isolate the variable h: Attempt to isolate the variable h on one side of the equation.Subtract –h from both sides of the equation to see if we can simplify it.(–h+10)−(–h)=(–h)−(–h)
Simplify the equation: Simplify both sides of the equation.On the left side, −h and +h cancel each other out, leaving us with 10.On the right side, −h and +h also cancel each other out, leaving us with 0.So, we have 10=0.
Determine if equation makes sense: Determine if the simplified equation makes sense.10=0 is not true for any value of h, which means there is no value of h that can satisfy the equation –h+10=–h.
