Question

este es el problema matematico ayudenme

Answer 1

Respuesta:

a)

x = 4

y = 2

b)

a = 3

b = 4

c)

m = 5

n = 3

Explicación paso a paso:

a)

2x = 10 - y

2x = 6 + y

10 - y = 6 + y

10 - 6 = y + y

4 = 2y

y = 2

2x = 8

x = 4

b)

8a = 7b - 4

48a = 42b - 24

6a = 3b + 6

48a = 24b + 48

42b - 24 = 24b + 48

18b = 72

b = 4

---

8a = 28 - 4

a = 24/8

a = 3

c)

2 + n = -4 + 3n

2 + 4 = 3n - n

6 = 2n

n = 3

---

m = 2 + 3 = 5
