Question

9.

A. 5x – 3y = 20

B. –3x – 5y = 20

C. –3x + 5y = 4

D. –3x + 5y = 20

Answer 1

Answer:

-3x+5y=20

Step-by-step explanation:

Standard form is given by ax+by=c

where a , b and c are integers

here we have an equation

so we first multiply the complete equation by 5 to get rid of the fraction

Now subtract 3x from both side to get the required standard form

-3x+5y=20

Explanation:

just move y to the side with x and move 4 to the other end
