Find the value of x.

Please help me!! All my points

x=10

Step-by-step explanation:

Hello There!

The shown angles are supplementary angles meaning that the sum of the two will be 180

so we create and equation

180=7x-3+12x-7

step 1 combine like terms

7x+12x=19x

-7-3=-10

now we have

180=19x-10

step 2 add 10 to each side

-10+10 cancels out

180+10=190

now we have

190=19x

final step divide each side by 19

19/19 cancels out

190/90=10

we're left with

x=10

i can't read the graph
