Okay, are you saying:
-a = 2, b = 2, c = 2, solve (a + b + c)
or
-2a * 2b * 2c(a + b + c)
Answer:
x=5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
The answer is A.
(a-1)(a-2)
a * a= a^2
a * -2= -2a
a * -1 = -1a = a
-1 * -2 = 2 because two negative signs make a positive.
Put them together:
a^2 - 2a - a + 2
= a^2 - 3a +2
3x + 12 - 5x = 22
-2x + 12 = 22
-2x = 22-12
-2x = 10
x = -5
