If im understanding your post this is what i get


y − 4x = 72

+ y + 4x = 2

_________


2y= 74


Y= 72/2


Y= 36


y − 4x = 72

35-4x=72


-4x=72-35


-4x=37


X= 37/-4


X= - 37/4 or -9.25


Answer in point (-37/4, 36)

Answer:

The solution is the point (-1,3)

Step-by-step explanation:

we have

y-4x=7 ------> equation A

2y+4x=2 ------> equation B

Adds equation A and equation B

y-4x=7\\2y+4x=2\\-------\\y+2y=7+2\\3y=9\\y=3

Find the value of x

Substitute the value of y in the equation A

y-4x=7

3-4x=7

4x=3-7

4x=-4

x=-1

The solution is the point (-1,3)

3. Resuelve el triángulo con A = 30º, a = 3 cm y b = 4 cm y comprueba que hay dos soluciones posibles.
Igoryamba

Answer:

41.8°

Step-by-step explanation:

Resolvemos esta pregunta usando la regla del seno

a / sin A = b / sin B

Estamos despejando el ángulo B

Por lo tanto:

3 / sin 30 = 4 / sin B

Cruz multiplicar

3 × sin B = sin 30 × 4

sin B = sin 30 × 4/3

B = arco sin [sin 30 × 4/3]

B = 41.81031 °

Aproximadamente = 41.8 °

Solve each linear equation for x. (A) –12x + 9 = –15x x = (B) 4.5x + 11.5 = 8.5x + 3.5 x = (C) 23x – 9 = 13x x =
mojhsa [17]

Answer:

A. x = -3

B. x = 2

C. x = 9/10

Step-by-step explanation:

(A) –12x + 9 = –15x

Collect like terms

9 = -15x + 12x

9 = -3x

x = 9 / -3

x = -3

(B) 4.5x + 11.5 = 8.5x + 3.5

4.5x - 8.5x = 3.5 - 11.5

-4x = -8

x = -8 / -4

x = 2

(C) 23x – 9 = 13x

-9 = 13x - 23x

-9 = -10x

x = -9 / -10

x = 9/10
