Q. Solve for a. Express your answer as a proper or improper fraction in simplest terms.−65−51a=−85Answer: a=
Rephrase the Question: First, let's rephrase the "What is the value of a in the equation −(65)−(51)a=−(85)?"
Add Constant Term: We have the equation: −(65)−(51)a=−(85). To solve for 'a', we need to isolate 'a' on one side of the equation. Let's start by adding (65) to both sides to move the constant term to the right side.
Combine Fractions: After adding (65) to both sides, the equation becomes: −(51)a=−(85)+(65).
Find Common Denominator: Now we need to find a common denominator to combine the fractions on the right side of the equation. The least common denominator (LCD) for 8 and 6 is 24.
Convert Fractions: We convert the fractions to have the common denominator of 24: −85 becomes −2415 and 65 becomes 2420.
Combine Fractions: Now we can combine the fractions on the right side: −2415 + 2420 = 2420 - 2415 = 245.
Isolate Variable: The equation now is: −(51)a=245. To solve for 'a', we need to divide both sides by −(51), which is the same as multiplying by −5.
Multiply by −5: Multiplying both sides by −5, we get: a=(245)×(−5)=−2425.
