Question

Place in order to solve the literal equation for: ab+c=x for a

a=x−cb
ab=x−c
−c −c
÷b ÷b

Answer 1

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

see the procedure

Explanation:

we have

`ab+c=x`

Solve for a

That means ---> isolate the variable a

Subtract c both sides

`ab+c-c=x-c`

`ab=x-c`

Divide by b both sides

`(ab)/(b)=(x-c)/(b)`

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