Question

Ayudenme a mi tarea 3x+5y=19 7x+2y=14

Answer 1

3x + 5y= 19
3x + 5(2) =19
3x = 19 - 10
3x = 9
x= 9/3
x= 3

3(3) + 5y= 19
5y =19 - 9
y= 10/5
y= 2
verificación
3(3) + 5(2) =19
9 + 10 = 19
19 = 19.


7x + 2y=14
7x + 2(2) =14
7x = 14 - 4
x = 10/7

7(10/7) + 2y =14
2y = 14 - 10
y = 4/2
y= 2

verificación
7(10/7) + 2(2) = 14
10 + 4= 14
14 = 14
