Question

can someone help explain how to do this please?
Write the equation y - 2 = 4(x + 5) in standard form.

A. 4x + y = 7
B. 4x - y = 3
C. 4x - y = -22

Answer 1

Standard form is ax+by=c where, 'a' is positive and all the coefficients are integers (not fractions or decimals)
y-2=4(x+5)
y-2=4x+20
y-22 = 4x (subtract 20 on both sides)
-22 = 4x-y (subtract y on both sides)
Answer: 4x-y = -22 (c)

Answer 2

any questions?

Answer 3

um no i think i get that now thank you very much for explaining exactly how to do it. :)
