Q. If −6x−5y=−9 is a true equation, what would be the value of −30x−25y?Answer:
Analyze Equation: Analyze the given equation.We are given the equation −6x−5y=−9 and asked to find the value of −30x−25y. Notice that −30x−25y is a multiple of −6x−5y.
Determine Multiple: Determine the multiple.To go from −6x−5y to −30x−25y, we multiply the entire equation by 5 because −6x×5=−30x and −5y×5=−25y.
Multiply by 5: Multiply the given equation by 5.Multiplying the entire equation −6x−5y=−9 by 5, we get:5×(−6x)−5×(5y)=5×(−9)−30x−25y=−45
Write Final Answer: Write down the final answer.The value of −30x−25y, given the equation −6x−5y=−9, is −45.
