Step-by-step explanation:
When moving the 4 to the other side, Viet was supposed to subtract 4 from each side, leaving 0 on the left, and 102-4 on the other side. 102-4=98, not 106. Viet added when he was supposed to subtract.
2x+y=6
3x+5y=9
y = 6 - 2x
3x + 5( 6-2x ) = 9
3x + 30 - 10z = 9
7x = 21
x = 3
y = 6 - 2(3)
y = 0
Answer: True
In math terms, an "image" is the result after a transformation has been applied. One or more transformations can happen here. The original figure is called the "preimage" or "before image" so to speak.
So we go from "preimage" to "image"
preimage ---> image
A maps to A'
B maps to B'
C maps to C'
D maps to D'
