How do i do these math problems?
1. 1/3y-5=7
2. 1/2t+4=13
3. y-8/2=11
4. 1/8(x + 10)=4

Okay lets solve your equations step by step! :)
1.
1/3y−5=7Step 1: Add 5 to both sides.1/3y−5+5=7+513y=12Step 2: Multiply both sides by 3.3*(1/3y)=(3)*(12)y=36
2.
12t+4=13Step 1: Subtract 4 from both sides.12t+4−4=13−412t=9Step 2: Multiply both sides by 2.2*(12t)=(2)*(9)t=18

3.
y−82=11Step 1: Simplify both sides of the equation.y−82=11 Simplify: (Show steps) y−4=11Step 2: Add 4 to both sides.y−4+4=11+4y=15

4.
18(x+10)=4Step 1: Simplify both sides of the equation.18(x+10)=4 Simplify: (Show steps) 18x+54=4Step 2: Subtract 5/4 from both sides.18x+54−54=4−5418x=114Step 3: Multiply both sides by 8.8*(18x)=8*(114)x=22

Well that was fun. :) Hope this helped! If you have any other questions or need further explanation just let me know!! :)

It says in the questions that it is 6.5?
