x=5/2
Step-by-step explanation:
1. 13=6x-2 (add 2 to each side)
2.15=6x (divide each side by 6)
3.15/6=x (simplify the fraction by dividing by 3)

Answer:z
Then variable is n
Variable is an alphabet that depend on number. Then the variable there is n
And the coefficient of the variable is 2
The coefficient is the number behind a variable

Add 3 to both sides
2n-3+3=7+3
2n=10
Divide both side by 2
2n/2=10/2
n=5
