The number that will be added to both side is the square of half the coeficient of x. i.e.
Answer:
Step-by-step explanation:
we have
Solve for y
That means-----> isolate the variable y
Subtract both sides -2
Divide by -5 both sides
Rewrite
Convert to function notation
Let
g(x)=y
The correct answer is

You can find this by first starting with the original question.

÷

Now to solve a division problem with fractions, you can always flip the second one and turn it into multiplying.

*

Now we can multiply numerator by numerator and denominator by denominator.

Then of course, we need to simplify. Since both are divisible by 3, we can divide both numbers by 3.
Answer:
Supplementary angles
Step-by-step explanation:
Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees.
Answer:
x=22/5
Step-by-step explanation:
multiply by 3 on both sides
7+x=6x-15
x=6x-22
-5x=-22
*-1 on both sides
5x=22
x=22/5
