Question

Solving the following systems of equation

7x+2y = -11
14x+10y=50
​

Answer 1

Answer:

x = -5

y = 12

Step-by-step explanation:

2(7x+2y= - 11)= 14x+4y= -22

14x + 4y = -22

-

14x + 10y = 50

----------------------------------------------------------------------------------------

4y - 10y = - 22 - 50

- 6y = -72

y= 12

-----------------------------------------------------------------------------------------

7x + 2(12) = -11

7x = -11 - 24

7x = -35

x = -5

---------------------------------------------------------------------------------------------------

Hope this helps!!!

Answer 2

Answer:

divide both sides by 7 and you will get x = 2y/7

find the gcf

GCF= 2

divide each term by it

2(14x/2 + 10/2)

simplify each term in parenthasis

2(7x+5y)
