WHAT IS -45 - x = - 18
SHOW STEPS PLEASE ALSO FOR
v - 55 = -43
AND -2 = n/10

x = -27, v = 8, n = -20.

Step-by-step explanation:

-45 - x = -18

+45         +45

-x  =  27

/-1       /-1

x = -27

v - 55 = -43

+ 55       +55

v  = 12

-2 = n/10

*10    *10

-20 = n

x = -27

v = 12

n = -20

Step-by-step explanation:

1) -45 - x = - 18

- Add 45 to both sides

-45 - x + 45 = -18 + 45

Group like terms:

-x + -45 + 45 = -18 + 45

Simplify the arithmetic:

-x = -18 + 45

Simplify the arithmetic:

-x = 27

- Isolate the X

Multiply both sides by-1

-x · -1 = 27 · -1

Remove the one(s):

x= 27 · -1

Simplify the arithmetic:

x= -27

2) v - 55 = -43

1. Group all constants on the right side of the equation

v - 55 = -43

Add 55  to both sides:

v - 55 + 55 = -43 + 55

Simplify the arithmetic:

v = -43 + 55

Simplify the arithmetic:

v = 12

3)  -2 = n/10

1. Swap sides

-2 = n/10

Swap sides

n/10 = -2

2. Isolate the n

n/10 = -2

Multiply to both sides by 10:

n/10 * 10 = -2 * 10

Group like terms:

1/10 * 10n = -2 * 10

Simplify the fraction:

n = -2 * 10

Simplify the arithmetic:

n = -20
