Question

resolver por cuaalquier metodo x+3y=7 5x-2y=-16

Answer 1

1. x = 1
y = 2

Comprobación:
1 + 3 (2) = 7
1 + 6 = 7
7 = 7

2. x = -4
y = -2

Comprobación:
5 (-4) - 2 (-2) = -16
-20-2(-2)=-16
-20+4=-16
-16=-16

Answer 2

x =7 - 3y
5x - 2y = -16
5(7 - 3y) - 2y = -16
35 - 15y - 2y = -16
-17y= -51
y=3 R//


x=7 - 3y
x= 7 - 3(3)
x=7 - 9
x= -2 R//
