<h2>Therefore x=2 and y= 1</h2>

Step-by-step explanation:

Given equations are

$y = 6x -11$ and $-2x -3y = -7$ .........(2)

⇒ $y - 6x = -11$ .......(1)

Equation (2)× 3 - Equation (1)

$-6x -9y -(y-6x) = -21 -(-11)$

⇔ $-6x -9y-y+6x=-21+11$

⇔-10y = -10

⇔y=1

Putting the value of y in equation (1) we get

$1 = 6x -11$

⇔x =2

Therefore x=2 and y= 1

Im not sure how to solve this please help

Effectus [21]

Look at the corresponding angle to 82, which is to the left of line b

It also measures 82 according to "corresponding angle theorem"

Then
angle x is equal to it as they are vertical pair of angle

so that, the measure of x equals 82 degree

I hope that helps
