Subtract 9x from 23x yields 14x. This was done by subtracting algebraically the variables.
All you need to do is substitue -2 into the equation for x,
h(-2) = 3(-2) + 1 = -6 + 1 = -5
Can't see all the options.
However, I'll guess and suggest B.
Not sure if this helped at all :P
Answer:
x = 10
Step-by-step explanation:
3x + 14 + 68 = 12x - 8
Combine like terms:
3x + 82 = 12x - 8
Subtract 3x from both sides.
82 = 9x - 8
Add 8 to both sides.
90 - 9x
Now, divide both sides by nine.
x = 10
