Answer 5

x/6-5=13

we want to find x so we need to isolate on one side of the equation.

lets add 5 to both sides so we keep it equal

x/6-5+5=13+5
x/6=18 now we mult by 6 both sides
(x/6)*6= 6*18------ 6 in denominator and numerator cancel

x=108

plug it in and check it

Answer 6

so x = 108

Answer 10

it is best you post problems indivually but i will do one more as an example

Answer 11

(12+4n)/3=8
so mult both by 3
12+4n=24 then subtract both by 12
4n=12 then we divide both by 4
n=3

plug it in and check it

you need to practice these to get good at them
