7m+2=7n−5

Swap sides so that all variable terms are on the left hand side.

7n−5=7m+2

Add 5 to both sides.

7n=7m+2+5

Add 2 and 5 to get 7.

7n=7m+7

Divide both sides by 7.

7n

=

7m+7

Dividing by 7 undoes the multiplication by 7.

Step-by-step explanation:

Semester Costs = 8*2858 =                     22864

Books / semester= 8 * 391 =                        <u>3128</u>

Total                                                            25992

5(n-4)=(4n-12)

First: Distribute 5 into n and -4.
5(n-4)=(5n)+(5*-4)= 5n-20.

Second: Subtract 4n from both sides to eliminate the variable from the right side of the equation.

(5n-20)=(4n-12)

n-20=-12

Next: Add 20 to both sides to eliminate the constant from the left side of the equation.

n-20=-12

n=8

The unknown number is 8.
