Q. Solve for y. Express your answer as a proper or improper fraction in simplest terms.43−74y=31Answer: y=
Isolate y term: Isolate the term containing y.To isolate the term containing y, we need to move the fraction (43) to the other side of the equation by subtracting it from both sides.(\frac{\(3\)}{\(4\)}) - (\frac{\(4\)}{\(7\)})y - (\frac{\(3\)}{\(4\)}) = (\frac{\(1\)}{\(3\)}) - (\frac{\(3\)}{\(4\)})
Calculate right side: Calculate the right side of the equation.\(\newlineWe need to find a common denominator to subtract (43) from (31). The common denominator for 3 and 4 is 12.(31)−(43)=(124)−(129)=−(125)
Write simplified equation: Write down the simplified equation.After subtracting (43) from both sides, we have:-\left(\frac{\(4\)}{\(7\)}\right)y = -\left(\frac{\(5\)}{\(12\)}\right)
Solve for y: Solve for y.\(\newlineTo solve for y, we need to divide both sides by −(74). This is equivalent to multiplying both sides by the reciprocal of −(74), which is −47.y=−(125)∗(−47)
Multiply fractions: Multiply the fractions.When multiplying fractions, we multiply the numerators together and the denominators together.y=12×45×7y=4835
