Answer:

y = -5/8

x = 7/24

Step-by-step explanation:

elimination

12x + 4y = 1 | ×1 |

6x - 2y = 3 | ×2 |

12x + 4y = 1

12x - 4y = 6

_________--

8y = -5

y = -5/8

elimination

12x + 4y = 1 | ×1 |

6x - 2y = 3 | ×2 |

12x + 4y = 1

12x - 4y = 6

_________+

24x = 7

x = 7/24

jeka94

The graph represented in the figure shows a set of linear equations each of which is represented a straight line.

Step-by-step explanation:

System of Equation can be referred to as an assortment of equations to be dealt with. Common examples include linear equations and non-linear equations such as a parabola, hyperbola etc.

Linear set of equations are the most simple of equation depicting a linear relationship between two variables.

E.g.  Y=4x+3

here y and x share a linear relationship which is defined by the straight-line graph "4x+3"

Similarly in the graph lines, two straight lines are depicted which symbolises that the et of the equation is linear in character.

VashaNatasha [74]
HEY THEIR!!

Taking commen 2 in RHS
p = 2 (L+W )

Divide by 2 on both sides.
p/2 = L+W

Subtract W on both sides.
p/2 - W = L

or L = p/2- W
