Answer: okay i’m not exactly certain but i can try to help. try setting the two equations equal to each other. since they are on the same side they are probably congruent. again, not certain
Step-by-step explanation:
9x + 11= 10x+5
move 10x to the right side and change it’s sign:
-10x + 9x + 11= 5
that leave you with -1x
-1x+11=5
-1x + 11-11 =5-11
-1x=-6
divide -1 by both sides, leaving you with
x=6
again, not sure but this is what i would try first. if this doesn’t work, try to set them equal to 180.
