Step-by-step explanation:

Step 1: Define

y = 3x - 2

Step 2: Rewrite

x =

Step-by-step explanation:

Given

y = 3x - 2 ( add 2 to both sides )

y + 2 = 3x ( isolate x by dividing both sides by 3 )

= x

47 - 90 = 43

43 - 180 = x

x = 137

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
