How do i solve this for a and b? 7/b-36=a/72=28/b
we were shown how to do multi steps but not multiple variables.

a=-3456

b=-21/36

Step-by-step explanation:

(7/b)-36=(28/b)

(7/b)-(28/b)=36

7-28=36b

-21=36b

-21/36=b

Since you found one variable substitute it in to find the other variable

28/b=a/72

28/(-21/36)=a/72

28 * (36/-21)=a/72

-48=a/72

72* -48 = a

a=-3456

a=-3456

b=-21/36

depending on others is critical to survival. my source is apex!
