You can put this solution on YOUR website! To solve for A, we need to get A all by itself on the left side of the equal sign. To do this, first add 1 to both sides of the equation:
8A - 1 + 1 = 19 + 1 ----->
8A = 20
Next, divide both sides of the equal sign by 8:
8A/8 = 20/8 ----->
A = 20/8
Finally, we can reduce the fraction to it's lowest terms by dividing both the numerator and denominator by 4, giving us our final answer:
A = 5/2
