Written algebraically, the equation is (2/A)=4.The first step is to move the variable A from the denominator. To do this, multiply both sides of the equation by A:A*(2/A)=4*AThe A in the denominator on the left is canceled out and we are left with:2=4*ATo solve for A divide both sides of the equation by 4:2/4=ATwo over four simplifies to one half, which equals A:1/2=A
3y + 2/4 =7 First, you subtract 2/4 (1/2) from both sides, resulting in 3y = 13/2 (6 and a half) Then, you multiply both sides by 1/3 (which is the same as dividing by 3), giving you y=13/6.
