Yes..

i am trying to find a

dont worry about the 7

u can get rid of it

the equation should look like dis now 3(2a-1)=7 times 4 = 28

so its = 3(2a-1)=28

ok now this part i dont get : o - Apr 4th 2008, 07:04 PMMathstud28Just follow my steps
$\displaystyle \frac{3(2a-1)}{7}=4$...using the distributive property $\displaystyle \frac{6a-3}{7}=4$...then by multiplying both sides by 7...you get $\displaystyle 6a-3=28$...adding three to each side you get $\displaystyle 6a=31$...then finally by dividing by six you get $\displaystyle a=\frac{31}{6}$
