Expert Answer

Step 1

Consider the first equation.

The given equation is –r = –3.

Solve the equation as follows.

 

 

-r-3
-3
-r
(Divide -1 both side)
-1
r = 3
r -3 3 3 (Subtract -3 both side
r-3 0
So, the given equation is -r = -3 can be written as r-3 0

Step 2

Consider the second equation and So...

t
4
t
4 -8.4
4
t 32
t32 0
t
-8 can be written as t+32 = 0
4
So, the given equation is
_=
as follows
Consider the third equation and solve the equation
-d =-8
3
4d 24
d -6
d+66+6 (Add 6 both sides
d 6 0
So, the given equation is -d =-8 can be written as d+6 = 0.
