How many solutions does the system below have?
3
y = -x + 8
4
3
y = -x - 5
4

I am taking the equations as 3y= -x+8

43y= -x-5

according to this there is only one unique solution

Step-by-step explanation:

se to identify solution identify type of line first

check the ratio of coffecient of variable and constant

if y1/y2 = x1/x2 = c1/c2 then the lines are coinciding and have infinite solution

if y ratio is not equal to x then 1 solution as I your question

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.
