Answer:

B (4, 9)

Step-by-step explanation:

Isolate one of the variable on the first equation

5 = -x + y

turn to

x = y - 5

Then insert this into the second equation

3 = 3(y - 5) - y

Simplify-

3 = 3y - 15 - y

3 = 2y - 15

Add 15 to both sides

18 = 2y

Divide by 2

9 = y

knowing y = 9 you can assume that -

(x, 9)

This means the only possible answer is B

What is the value of x? 20 35 60 70

fenix001 [56]

The given angles are =

(x+40)° and 3x°

As the given angles are opposite to each other on the intersecting lines, so they are vertical angles. These are congruent or equal.

So, $x+40=3x$

$2x=40$

$x=20$

Hence x = 20°

The given angles are =

(x+40) = 20+40 =60°

3x = 3*20 =60°
