Q. How many solutions does this equation have?−9y=5−9yChoices:(A)no solution(B)one solution(C)infinitely many solutions
Write Equation: Write down the given equation.−9y=5−9y
Isolate Variable: Attempt to isolate the variable y on one side of the equation by adding 9y to both sides.−9y+9y=5−9y+9y
Simplify Equation: Simplify both sides of the equation. 0=5
Analyze Simplified: Analyze the simplified equation.The equation 0=5 is never true, regardless of the value of y.
Conclude Solutions: Conclude the number of solutions based on the analysis.Since the equation 0=5 is a contradiction, there are no values of y that can satisfy the equation. Therefore, the equation has no solution.
