Question

*If you Answer a random answer just for points you WILL be reported*

Answer 1

Ok

Part A.It should be (4*n)-5=(3*n)-2

Part B.N=3

Part C.First you Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                (4*n)-5-((3*n)-2)=0

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

1.1      Solve  :    n-3 = 0

Add  3  to both sides of the equation :

                     n = 3

Hope I could help you

Answer 2

4n-5=3n+2

subtract 3n from each side

4n -5 -3n = 3n +2 -3n

n -5 = 2

add 5 to each side

n-5+5 = 2+5

n = 7

To solve a equation with a variable, you need to get the variable alone.  I got the variable on the left hand side and the constants on the right hand side
