Solve for b.
ab + c = d
Ob = a + c/d
b = a/(c-d)
b = (d - c)/a

b = ( d-c)/a

Step-by-step explanation:

ab + c = d

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

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
