Help pls ...................................

Answer 1

x=-6.3÷3=2.1

X=3×12=36

X=3÷1.2=2.5

X=-1.2×-0.3=0.36

Answer 2

1). -3x = 0.3

==> x = 0.3/(-3)

==> x = -0.3/3

==> x = -0.1

_______________

2). x/3 = -12

==> x = -1/6

___________________

3). -1.2x = -30

==> x = -30/(-1.2)

==> x = 30/1.2

==> x = 300/12

==> x = 25

__________________

4). x/(-1.2) = -0.3

==> x = -0.3 × (-1.2)

==> x = 0.36
