Q. Solve for b. Express your answer as a proper or improper fraction in simplest terms.43b−65=−41Answer: b=
Isolate variable b: First, we need to isolate the variable b on one side of the equation. To do this, we will start by adding 65 to both sides of the equation to move the constant term from the left side to the right side.43b−65+65=−41+65
Simplify both sides: Now, we simplify both sides of the equation by combining like terms. 43b=−41+65
Find common denominator: Next, we need to find a common denominator to combine the fractions on the right side of the equation. The common denominator for 4 and 6 is 12. 43b=[−41×33]+[65×22]43b=[−123]+[1210]
Add fractions: Now we add the fractions on the right side of the equation.(43)b=[−(123)+(1210)](43)b=(127)
Divide by (3)/(4): To solve for b, we need to divide both sides of the equation by (3)/(4). To do this, we multiply both sides by the reciprocal of (3)/(4), which is (4)/(3).b=(7)/(12)×(4)/(3)
Multiply numerators and denominators: Now we multiply the numerators and the denominators.b=12×37×4b=3628
Simplify fraction: Finally, we simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4. b=428/436b=97
