Question

Find the value of x

pls helpp​

Answer 1

x=5

Explanation:

we have,

12x+19+22x-9 = 180

34x+19-9 = 180

34x + 10= 180

34x = 180-10

34x = 170

x=170/34

x=5

Answer 2

x=5

Explanation:

Since these are supplementary angles, we will have to add the two equations shown together to equal 180º.

`12x+19+22x-9=180`

`34x+10=180`

`34x=170`

`x=5`
