A letter or symbol is used to represent an unknown quantity
Answer:
Its 0 because thats the only value not bigger than 4
Step-by-step explanation:
Lets say that the first number is x and the second number is y.
from the question we know that:
y=-3x and x+y=-4
from there, you need to replace the y in the second equation with -3x since we know that is what y equals so we can have an equation with only one variable.
x+-3x+-4
Then you solve for x.
-2x=-4
x=2
then you find y with the fact that y=-3x
y=-6
Answer:
Multiply 4 to the terms inside the parentheses.
(12x+8)-2
Remove the parentheses and equate it to zero.
12x+8-2 = 0
Simplify
12x+6 = 0
Transpose 6 to the other side.
12x = -6
Divide bith sides by 12.
12x/12 = -6/12
Simplify.
x = -6/12 or -½
Answer: x > 3
Step-by-step explanation:
In order to find x, we must isolate it first.
Add one to both sides. It's now 4x < 12.
Now we divide both sides by 4, remember that every time we divide or multiply we must flip the inequality symbol.
The final answer is x > 3
