Write each equation in standard form: −9 = −4x − 7y

Question

Putting the problem -9 = -4x -7y into standard form.

Answer 1

-9 = -4x -7y

multiply (or divide) by -1 to get

9 = 4x +7y

4x +7y = 9 is in standard form (ax +by = c where a= 4, b=7, c = 9)

or -4x -7y = -9 which is an equivalent equation in standard form
