For the equation 2n-3=7

1. What is the variable?

2. What is the coefficient of the variable?

1. The variable is n

2. The coefficient is 2

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

And the value of the variable is

2n-3=7

Add 3 to both sides

2n-3+3=7+3

2n=10

Divide both side by 2

2n/2=10/2

n=5
