Answer:
that's a hundred and three because n which is the variable * 100 + 3 equals 103
Answer:
n = -7
Step-by-step explanation:
-6n + 3 = 45
-3 -3
--------------------
-6n = 42
Divide both sides by -6
42/-6 = -7
n = -7
Division property of equality, because you have to divide 8x and 80 by 10
Subtract four from both sides. That'll put both numbers without a variable on one side, and the number with the variable is by itself.
