Answer:
-16.4, (commutative property)
Step-by-step explanation:
(add, because they are both negatives) -5.2+(-8.4)= -13.6
Then add the (-2.8): -13.6 + (-2.8) = -16.4
Thats your first equation!!!
do the same thing for the other one, and by the way it the same answer.
Its commutative prop because its just switching positions and its adding negatives.
<span>"Simplifying
0.2y = 0.5x + 0.1
Reorder the terms:
0.2y = 0.1 + 0.5x
Solving
0.2y = 0.1 + 0.5x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '0.2'.
y = 0.5 + 2.5x
Simplifying
y = 0.5 + 2.5x"</span>
