-84 = 3(5n + 2)
Multiply everything in the parenthesis.
-84 = 3(5n + 2)
3*5n + 3*2
-84 = 15n + 6
Subtract 6 from both sides
-84 = 15n + 6
-6 -6
-90 = 15n
Divide 15 from both sides
-90 = 15n
--------------
15 15
-6 = n
-6 is your answer.
The answer would either be (-3,5), (5,-3), (9,-7), or (-7,9). I forget where the <em>x </em>and <em>y</em> go, but those are your answer choices.
Y=3 if you want to know the process lemme know
C is your answer because you count 1 square a block
