quations ?.

2x

+1=9, 7k-3=32, 5(n-8)=25 2(2t-1)=14

8x-1=63 ,2x-5=15,

**JJ**, Wednesday, March 30, 2011 at 8:18amOkay so

2x+1=9

We move the 1 over to the other side of the equal sign, which means the equation now reads

2x=9-1

solve this

2x=8

now we divide both sides by 2 (its the multiplier of x and we want to split them apart)

x=4

TaDa!

With your brakets

2(2t-1)= 14

Okay so firstly we divide both sides by 2

t-0.5 = 7

Then we move the 0.5 over the equal sign

t = 7 + 0.5

t = 7.5

TaDa

Now if you do the rest of your equations they should work.

Hope this helps

:)
