You can do anything you want to one side of an equation.
You'll usually apply an inverse operation to make the side
simpler, for example to get rid of the 'x', or to get rid of the
fractions on that side.
But when you do something to one side of the equation,
you MUST do exactly the same thing to the other side too.
If you don't, then you have changed the equation to a
different one, and the solution to the one you have now
is not the solution to the original one.
Very simple example:
Solve the equation 2x = 2
Correct solution:
Divide each side by 2 : x = 1
Incorrect solution:
Divide the left side by 2 : x = 2
The line
<span>The sum of twice x and 3 times y is less than 6
is the same as
2x + 3y < 6
which can be transformed into
y < -2x/3 + 2
and
</span><span>y must be greater than 1 less than twice the x
is
y > 2x - 1
The solution is represented by the first figure.</span>
Answer:
Q = (1, -5)
Step-by-step explanation:
Reflection over x-axis (x,y) → (x,-y)
B = (1,5)
Q = (1,-5)
2:3
it was originally 8:12, but it has to be simplified. 2/3 can also work as an answer.
Answer:
8
Step-by-step explanation:
2x2 is 4 and x 2 is 8. I think im right?
