What is the value of x in the solution to the following system of equations? (5 points)

x − 2y = 2
3x + y = 6

x = 2 and y = 0

Step-by-step explanation:

x - 2y = 2

3x + y = 6

using the substitution method, we solve the first equation for 'x' to get

x = 2y + 2

plug that into 'x' in the second equation

3(2y + 2) + y = 6

6y + 6 + y = 6

7y = 0

y = 0

find 'x':

3x + 0 = 6

x = 6/3

x = 2

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
