Question

Calcula:
2(x+1) + 3 (y-1)= 13
4(x+1) - 8 (y-1)=12

Answer 1

1)

$7 - \frac{3}{2}$

2) 2y

Explicación paso a paso:

1)

2(x+1) + 3 (y-1)= 13

2x - 1 + 34 = 13

2x= 13 + 1 - 3y

2x = 14 - 3y

$7 - \frac{3}{2}$

2)

4(x+1) - 8 (y-1)=12

4x + 12 - 8y = 12

4x - 8y = 0

4x = 8y

x = 2y

que tengas un hermoso día :D
