Answer 4

none

Answer 5

in that case, idk.... :(
sorry....

Answer 6

how about this??

Answer 7

you'll have to solve a system of two equations with two unknowns:

3a + b = 90
7a = b + 90

do you understand where these equations came from?

Answer 8

how?

Answer 9

how will i compute these?

Answer 10

can you show me how to solve this

Answer 11

are you asking how i got these equations OR how do you solve this system of equations?

Answer 12

how to solve

Answer 13

just like solving any system of linear equations, you can do elimination or substitution....
these terms ring a bell?

Answer 14

maybe if i write the equations this way you'll prolly be able to do elimination:

3a + b = 90
7a - b = 90

add these equations to eliminate the "b" unknown....

Answer 15

sorry.... i gotta make like a baby and head out.....
gotta go... cya....
