3x+7=19
-7 -7
which cancels out 7 and leaves you with
3x=12
you then divide both sides by 3 to get
x=4

1/2x-1=5
+1 +1
which cancels out 1 and leaves you with
1/2x = 6
you then divide both sides by 1/2 leaving you with
x=12
sorry if this answer is a little late

Dilation is a transformation of scaling that requires a center of scaling and a factor of scaling.
Similarity is a relationship between two figures when there is a special transformation that transforms one figure into another.
This transformation can include any combination of rotation, shift and dilation.
That's why a pair of a source and its image after dilation are similar, but not all similar figures can be connected by dilation. For instance, rotation and/or shift transform a figure into another, similar one to the original, but not related through dilation..

(x + 4)² = 20 ← equivalent equation
