Six times Jason's collection of books and one-third of Nathan's collection add up to 134 books. One-third of Jason's collection

siniylev [52]

6j+ $\frac{1}{3}$ n=134

$\frac{1}{3} j+n=31$ you multiply this by 18

6j+18n=558
6j+1/3*n=134
___________(-)

53n/3=424 => 53n=1272 => n=24

You put n in the first equation:
6j+8=134
6j=126 => j=21

Final answer: Nathan has 24 books and Jason 21.

Ab + c = d solve for B

Zepler [3.9K]

Answer:

b = (d-c)/a

Step-by-step explanation:

ab + c = d

We want to solve for b, so we need to get b alone

Subtract c from each side

ab+c-c = d-c

ab = (d-c)

Divide each side by a

ab/a = (d-c)/a

b = (d-c)/a
