15−2x−8−3x=−x−12+4x+43
now combine all the like terms on each side.
Add -2x and -3x
subtract 15 and -8....you subtract because the sign are different
now do the same for the other side
−5x+7=−x−12+4x+43
−5x+7=3x+31
bring the x value from the right side to the left side.
−5x+7−3x=31
combine like terms on left side
−8x+7=31
now move +7 to the right side which become..
−8x=−7+31
−8x=24
we will need to single out X by dividing

answer: X= -3
Answer:
yeah i dont know this one i tried to do it but i came up with a crazy answer
(7^x - cbroot(729)) / 2z
(7^7 - 9)) / 2(4)

40 / 8
5
I hope this helps out!
If I’m reading this correctly, the correct answer would be 11, because AB is congruent to EF, and they gave you AB
