Question

Write the equation 7Y= 21X +0.7 in standard form identify a, B, and C

Answer 1

9514 1404 393

Answer:

30x -10y = -1

(A, B, C) = (30, -10, -1)

Explanation:

We can multiply by 10 to clear the fraction:

70y = 210x +7

Now, we can remove a common factor of 7 from the coefficients:

10y = 30x +1

Subtracting 10y+1 puts this in standard form.

30x -10y = -1

The coefficients are A=30, B=-10, C=-1.
