Question

Write the equation 9y=12x+0.2 in standard form identify A B C

Answer 1

60x-45y=-1

A = 60

B = -45

C =-1

Explanation:

`9y=12x+0.2\\Re-write\:0.2\:as\:1/5-12x =-9y+(1)/(5) \\\\Multiply\:all \:terms \:by\:-1\\-1(-12x=-9y+1/5)\\\\12x =9y-(1)/(5) \\\\Multiply\: through\: by \:5\\5(12x =9y - (1)/(5) )\\\\60x = 45y -1\\\\60x-45y =-1`

Answer 2

Standard form: Ax+By=C
9y=12x+0.2
-12x+9y=0.2
12x-9y=-0.2
A=12
B=-9
C=-0.2
