What is y + 4 = 2(x - 5) in standard form?

a. -2x + y = -14
b. y = 2x - 14
c. y + 4 = 2x - 10
d. 2x - y =14

A
Standard is number with X + or - number with y = #

Y+4= 2x-10
Take 4 to the right change sign
Y= 2X-10-4
Y= 2X-14
Take 2x to the left side change sign
-2X+Y=-14

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
