Write the equation 8y = 1/12x – 0.8 in standard form. identify a, b, and c.

a. 480x + 5y = –48 where a = 480, b = 5, and c = -48

b. 480x – 1y = –48 where a = 480, b = –5, and c = -48

c. 5x – 480y = 48 where a = 5, b = –480, and c = 48

d. 1x + 96y = 9.6 where a = 1, b = –96, and c = 0.8

Step-by-step explanation:

Let's first write all the coefficients in fraction form, noticing that 0.8 is the same as , and then group the term in x and the term in y on one side of the equal sign, moving the pure numerical coefficient to the other side:

Now find the LCD for the existing denominators (5 and 12). This is: LCD = 60

Use the LCD we just found, to multiply both sides of the equation, so as to get rid of all denominators in the equation:

notice that our equality matches answer C provided.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
