Question

for which equation is the order steps to first divide both sides by 6 and then add 8 to both sides

Answer 1

You need an equation where the variable is inside a factor multiplied by 6 and also has −8 inside that factor. In general:
6(x − 8) = b
To solve you would
1) divide both sides by 6 → x − 8 = b/6
2) add 8 → x = b/6 + 8

Example: 6(x − 8) = 30
Divide by 6: x − 8 = 5
Add 8: x = 13
