Explanation:

The solution set for a system of equation is the set of points where the graphs of the equations intersect.

__

<h3>general case</h3>

A system will have <em>one solution</em> if there is a <em>single point of intersection</em> of the graphs of the equations.

A system will have <em>no solutions</em> if the graphs have <em>no points of intersection</em>.

A system will have an <em>infinite</em> number of <em>solutions</em> if the graphs <em>intersect at an infinite number of points</em>.

_____

<h3>linear equations</h3>

When the equations are linear equations, their graphs are straight lines. If the lines have different slopes, they must intersect at exactly one point: there will be one solution.

If the lines have the same slope, there are two possibilities:

  • the lines are parallel -- no solutions
  • the lines are coincident -- infinite solutions

The attached graph illustrates these cases.

  • the red and blue lines are the graphs of a system of equations with one solution. Those lines have different slopes
  • the blue and green lines are the graphs of a system of equations with no solution. Those lines are parallel.
  • The red and (dotted) purple lines are the graphs of a system of equations with infinite solutions. Those lines are coincident.

Nadusha1986 [10]

Answer:

1) 4

2) 45

3) 104

Step-by-step explanation:

1)

let x be your number.

((6x+8)/4)-5 = 3

add 5

(6x+8)/4=8

multiply by 4 to get rid of the denominator

6x+8=32

subtract 8

6x=24

divide by 6

x=4

2) Same type. (this time I won't explain every step)

let x be your number

((x/9)-8+6)*7 =21

(x/9)-8+6=3

(x/9)-2=3

x/9 = 5

x=45

3) Same type... Again

let x be your number

(((x-4+11)*2)/6)-8 = 29

((x-4+11)*2)/6=37

(x-4+11)*2 = 222

x+7=111

x= 104
