The product of 13 and the difference between a number and 7 yields 2 times the number plus 3

13(n-7)=2n+3
expand
13n-91=2n+3
minus 2n both sides
11n-91=3
add 91 both sides
11n=94
divide both sides by 11
n=94/11

Where is the problems

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
