5x +y = 6
5x + 3y = -4
multiply top equation by -1 and bottom by 1
-5x -y = -6
5x+3y = -4
solve and get
2y = -10
y = -10/2
y = -5
answer is -5
It is true due to the commutative property of multiplication. If all of your operations are multiplication, then the integers can move around and you can still get the same answer.
^This is only true if you meant to type (1.8x3)x2.1=(1.8x2.1)x3
If you meant what you typed, then the equation is false. The left side would be 3 times the value of the right side due to the 3 being on the left side and not the right side while without the 3 the two sides would be equal.

Answer:
4/7
Step-by-step explanation:
Easy peasy pumpin easy
split it up (make in to net and unfold or something)
2 triangles (identical)
2 side rectangles (identical
1 base
area of rectangle=lh or wl etc
area of triangle=1/2bh
triangles
b=16
h=6
area of triangle=1/2*16*6=48
times 2 since 2 of them
48*2=96
2 side rectangles
10 by 7
10*7=70
times 2 since 2 of them
70*2=140
base
16by 7
16*7=112
add them
96+140+112=348
answer is C
