Answer:

F=full page  H=half page

40H+75F=800

H+F=13  so H= 13-F  substitute 13-F for H in the first equation.

40(13-F)+75F=800

520-40F +75F=800

35F= 280  so F=280/35=8

8 fullpage and  5 halfpage ads

4t-7=8t+3. help pls. 90 points if you get it right
DerKrebs [107]
Simplifying
4+-7=8t+3

Reorder the Terms 
-7+4=8t+3

Reorder The terms again
-7+4t=3+8t

Solving for the variable T

Move all terms containing t to the left, and all other terms to the right

Add -8t to each side of the equation

-7+4t+-8t=3+8t+-8t

Combine like terms

4t+-8t=-4t

7+-4t=3+8t+-8t

Combine like terms 

8t+-8t=0

-7+-4t=3+0
-7+-4t=3

Add 7 to each side of the equation

-7+7+-4t=3+7

Combine like terms

0+-4t=3+7
-4t=3+7

Combine like terms 3+7=10

-4t+10

Divide each side by 4
t= -2.5

Simplifying
t= -25
