Answer:
-12.8x - 20y + 8.4
Step-by-step explanation:
To do this you just multiply everything by negative 4
so we have 3.2x*-4 + 5y*-4 - 2.1*-4
This gives us
-12.8x - 20y + 8.4
The last term is positive because we multplied a negative by another negative
90/ [10(3^2 - 4)]
= 90/ [ 10 (5)]
= 90/ 50
= 9/5
= 1.8
