Becky and tommy are asked to solve -4x-25=8x+15 identity where one of them made an error
ololo11 [35]
I feel sorry for Becky and Tommy. The one who didn't come up with x=-10/3 made an error.

first bring 8x to the left and -25 to the right and simplify:

-4x-8x = 25+15 => -12x = 40

x = -40/12 = -10/3
