Expanding both sides of the equation, we get:
х+7х+7х+7х+7х+7х+7 = 6−х6-х6−х6−х6-х6−х х^2 + 14х + 49 = 36 - 12х + x^2Combine like terms:14х + 49 = -12х + 3626х + 49 = 3626х = -13х = -13/26х = -1/2
Therefore, the solution to the equation х+7х+7х+72=6−х6-х6−х2 is х = -1/2.
Expanding both sides of the equation, we get:
х+7х+7х+7х+7х+7х+7 = 6−х6-х6−х6−х6-х6−х х^2 + 14х + 49 = 36 - 12х + x^2
Combine like terms:
14х + 49 = -12х + 36
26х + 49 = 36
26х = -13
х = -13/26
х = -1/2
Therefore, the solution to the equation х+7х+7х+72=6−х6-х6−х2 is х = -1/2.
