use backtracking to solve each e
+1=9, 7k-3=32, 5(n-8)=25 2(2t-1)=14
7th grade -
We move the 1 over to the other side of the equal sign, which means the equation now reads
now we divide both sides by 2 (its the multiplier of x and we want to split them apart)
With your brakets
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
Now if you do the rest of your equations they should work.
Hope this helps
