Answer:
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
Answer:
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
