Answer:
X = -5
Step-by-step explanation:
-6x + 18 = 7 - (4x + 9)
first we simplify the parentheses.
distribute the invisible number one created by the negative sign in front of the parentheses to get -6x + 18 = 7 - 4x - 9
then simplify further by subtracting 9 from the right side, leaving you with
-6x + 18 = -2 - 4x
next, add 2 to both sides to isolate the variable.
-6x + 20 = -4x
then, to isolate the variable further add 6x to both sides.
20 = -4x
divide both sides by -4 to isolate the variable
-5 = x
so, x = -5
For this case we have the following polynomials:
To add the polynomials we must add term by term according to the degree, that is, add similar terms:
The first polynomial has a cubic term and the second does not, so the sum will have only the cubic term of the first polynomial. The same applies to the quadratic term of the second polynomial.
