Question

10⁴/10⁷=


4x+3y=10
2x+5y=12

11⁶ x 11⁵

Answer 1

Respuesta:

10⁴/10⁷= 10-³ (el exponente es -3)

4x+3y=10

(2x+5y=12) . 2

4x. + 3y = 10

-

4x + 10y = 24

0x - 7y = - 14

-7y = -14

y -14/(-7)

y = 2

4x+3y=10

4x + 3.2 = 10

4x = 10 - 6

x = 4/4

x = 1

VERIFICAMOS

4x+3y=10

4 . 1 + 3 . 2 = 10

4 + 6 = 10

10 = 10 VERIFICADO

2x+5y=12

2 . 1 + 5 . 2 = 12

2 + 10 = 12

12 = 12 VERIFICADO

11⁶ x 11⁵ = 11¹¹
