Question

Write the equation y - 2 = 2(x - 3) in standard form.
A. y - 2x = 4
B. 2x - y = -6
C. 2x + y = 6
D. 2x - y = 4

Answer 1

y - 2 = 2(x - 3)
multiply out the 2 on the right side:
y-2=2x-6
bring the y over to the right by subtracting to both sides:
y-2-y=2x-6-y
-2 = 2x-y-6

add 6 to both sides:
-2+6=2x-y-6+6
4=2x-y
