y = 7x + 8

y = x + 20

7x + 8 = x + 20 transitive of equality

6x + 8 = 20 subtract x from both sides

6x = 12 subtract 8 from both sides

x = 2 divide both sides by 6

Hope This Helps! Have A Nice Night!!

It's A because if you replace x with 2 and y with 22 both of the equations will work

Calcular: E = (sec245o + tg45o) ctg37o - 2cos60o

Answer:

$-2.813$

Step-by-step explanation:

Se simplifica inicialmente la fórmula en términos de las funciones trigonométricas fundamentales (Initially, the formula is simplified in terms of fundamental trigonometric functions):

$(\sec 245^{\circ} + \tan 45^{\circ} )\cdot \cot 37^{\circ} - 2\cos 60^{\circ}$

$\left(\frac{1}{\cos 245^{\circ}}+\frac{\sin 45^{\circ}}{\cos 45^{\circ}} \right)\cdot \left(\frac{\cos 37^{\circ}}{\sin 37^{\circ}} \right) - 2\cdot \cos 60^{\circ}$
