Question

Solve for b. ab + c = d

Answer 1

`b=(d-c)/(a)`

Explanation:

For this problem, we are essentially making b the subject of the expression to get our result.

`ab+c-c=d-c\\ab=d-c\\(ab)/(a)=(d)/(a)-(c)/(a);\:\mathrm{assume}\:\:a\\e \:0\\(ab)/(a)=(d)/(a)-(c)/(a)\\(ab)/(a) = b\\(d)/(a)-(c)/(a)\\= (d-c)/(a)\:\:\mathrm{Reminder:\:a\\eq 0}\\b=(d-c)/(a)`
