Question

Solve the equation, ab + 10c = 9 , for the variable, a

Answer 1

`a=(9-10c)/b`

Explanation:

we have

`ab+10c=9`

Solve for the variable a

That means----> isolate the variable a

Subtract 10c both sides

`ab+10c-10c=9-10c`

`ab=9-10c`

Divide by b both sides

`ab/b=(9-10c)/b`

`a=(9-10c)/b`
