{2x+5y=26} {3x+4y=26}

NeTakaya

2x + 5y = 26....multiply by 3
3x + 4y = 26...multiply by -2
------------------
6x + 15y = 78 (result of multiplying by 3)
-6x - 8y = - 52 (result of multiplying by -2)
-----------------add
7y = 26
y = 26/7 (or 3 5/7)

2x + 5y = 26
2x + 5(26/7) = 26
2x + 130/7 = 26
2x = 26 - 130/7
2x = 182/7 - 130/7
2x = 52/7
x = 52/7 * 1/2
x = 52/14 which reduces to 26/7 (or 1 5/7)

solution is : (26/7, 26/7)

Emath has a stockpile of 1850 algebra textbooks. They are being purchased at a steady rate of 120 books per week. Write a linear

labwork [276]

Answer: b = 1850 - 120w

Step-by-step explanation:

Let w represent the number of weeks for which the books are purchased.

They are being purchased at a steady rate of 120 books per week. This means that the number of books purchased after w weeks would be 120w.

The total number of algebra textbooks that she had initially is 1850

If b represents the number of books left after w-weeks of sales, then the linear function that models the number of books left after w weeks would be

b = 1850 - 120w
