In exercises 8-10, write a system of linear equations that has the ordered pair as its solution. (-6, -2)
Anika [276]

Answer:

(8) x + y = -8 and 2x - y = -10

(9) 3x - y = -54 and 4x + y = -30

(10) x + y = 2 and x - y = 2

Step-by-step explanation:

Given [Missing from the question]

(8).\ (-6,-2)\ \\ (9).\ (-12,18)\ \\ (10).\ (2,0)

Required

Write a system of linear equations

The solutions to this question is open and have different solutions

Solving (8) (-6,-2)

Let the equations be: x + y and 2x - y

x + y = -6 - 2

x + y = -8 --- (1)

2x - y = 2 * (-6) - (-2)

2x - y = -10 -- (2)

So, the equations are:

x + y = -8 and 2x - y = -10

Solving (9) (-12, 18)

Let the equations be: 3x - y and 4x + y

3x - y = 3 *(-12) - 18

3x - y = -54

4x + y = 4 * (-12) + 18

4x + y = -30

So, the equations are:

3x - y = -54 and 4x + y = -30

Solving (9): (2,0)

Let the equations be: x + y and x - y

x + y = 2 + 0

x + y = 2

x - y = 2 - 0

x - y = 2

So, the equations are:

x + y = 2 and x - y = 2

PLEASE, PLEASE, PLEASE HELP ME!!!! I NEED THE ANSWER IN ONE HOUR!!! Ben has 57 toys. 15 of them are new, 9 are his favorite ones
storchak [24]
So.... there are a total of 57 toys, which the new and favorites ones are not going to be sold.

The equation would ultimately go into 57 - (15+9+2), which would equal to 31. Ultimately, he sells 31 toys and have 26 left over.

in short, subtracting 57 with the sum of 15+9+2 would equal to 31 toys which means that he sells the 31 toys.
