Solve equations

12x + 47 = 203
4/5k + 19 = 67

12x + 47 =203

12x = 203-47

12x =156

x = 156/12

x=13

OK DiD YOU UNDER STAND

4/5k+19 =67

4/5k = 67-19

4/5k=48

k=48×5/4

k=240/4

k=60

OK, HOPE YOU UNDER STAND

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.
